Experienced athletes share their insights in answering this question:
Body armour can be made
from a number of different types of woven or non-woven materials. One of the
first fibres used for modern ballistic-resistant material was Kevlar , which is made by DuPont.
Other materials include Spectra , made by Honeywell
(formerly AlliedSignal); Twaron , made by Accordis
(formerly Akzo Nobel). These materials are manufactured in a variety of styles
and can be woven or non-woven (laminated). Hard (non-fabric) armour plates can
be made from a number of materials, including metals, ceramics and other
composite materials.

How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

Hard body armour is made of metal or ceramic plates. Soft body armour mainly consists of layers of fabric made of high performance fibres.
Today`s body armor systems may contain some steel (though only in small amounts), but they are largely made of Kevlar. Kevlar is a type of aramid. It is a material that DuPont developed. It is a synthetic fiber that offers protection against bullets and shrapnel.
Level IV armor is the highest rating of body armor currently available, and it will stop armor-piercing rifle threats. It can withstand up to 30-06 M2ap steel core armor-piercing rounds with a mass of 166 grains and a velocity of 2880 ft/s.
One of the most commonly used materials is Kevlar®, a synthetic fiber developed by DuPont in the 1960s. Kevlar® is five times stronger than steel by weight, making it an excellent choice for body armor. Another popular material is Dyneema, a high-strength polyethylene fiber that is even lighter than Kevlar®.
Body armor plates are made up of strong fibers that are tightly woven in a perpendicular weave to create a solid sheet of material. The fibers are often twisted to increase strength, density and thickness. To make the body armor plate more solid, it is coated with resin, plastic and/or other materials.
Filtered Water, Pure Cane Sugar, Coconut Water Concentrate, Citric Acid, Dipotassium Phosphate (Electrolyte), Ascorbic Acid (Vitamin C), Magnesium Oxide (Electrolyte), Natural Tropical Punch Flavor With Other Natural Flavors, Calcium D-Pantothenate (Vitamin B5), Niacinamide (Vitamin B3), Alpha-Tocopheryl Acetate ( …
Nowadays, the best material for body armor is polyethylene. Because many soft and hard body armor products are made from it. Kevlar, steel, and Polyethylene (PE) are the most used materials in the production of body armors.
Titanium armor and helmets are similar in hardness to hardened spring steel. It has approximately 35-40 HRC by Rockwell. But the most important thing is that titanium is 40% lighter than any steel. This quality gives titanium an obvious advantage when compared to tempered steel.
UL 752 Level 7 Bullet Resistant Barriers

Most commonly used as a protection barrier against multiple shots from a military assault rifle, such as the M-16, and the like, with muzzle energy of 1158-1402 foot-pounds (1570-1901J).

Level 4 / Level IV Ceramic Plates

Ceramic plates are the most commonly used material for level 4 body armor. They are made from a combination of ceramic and aramid fibers, which are woven together and bonded with resin. The result is a hard, lightweight plate that can stop most high-powered rounds.

Buying and wearing body armor is legal on the federal level in the United States, but some states have specific laws concerning the buying and selling of these products.
The protective technology currently being produced by the Russians is known as Superthread, made from ultra-high-molecular-weight polyethylene. The reason it`s so lightweight is that polyethylene is the same plastic water bottles, grocery bags, and pretty much half the stuff in your house is made from.
Spider silk is highly flexible, extremely stretchable, surpasses steel in strength, and most importantly, can be formed into a mesh that would stop a bullet.
Body armor is comprised of very strong non-woven and/or woven ballistic fibers. The material will stop a bullet similar to how a net will stop a tennis ball or volleyball.
The ceramic plate used in the CAP product is designed to completely capture the bullet without penetrating the officer or bystanders that may be in the line of fire. Unlike soft armor, the officer will not be incapacitated and can respond effectively after being shot.
BODYARMOR is perfectly safe for kids to consume. BODYARMOR Sports Drink and BODYARMOR LYTE is caffeine-free gluten-free, and made with natural ingredients without any artificial sweeteners, flavors, or dyes.
Replenishing with water is important. Even though you may be trying to replenish these nutrients to help your body function, it`s not safe to overload your body with the constant sources of electrolytes and calories that are contained in a sports drink, despite what many may have heard.
Level/Type III Body Armor

A 7.62mm FMJ is normally fired from an AK-47 style rifle or a sniper rifle. Level III will stop most of all 5.56mm and 7.62mm bullets, but will not defeat military-grade armor-piercing ammo.

When all of the energy moving the bullet forward has been transferred through collisions, the bullet stops. Water molecules are packed much more tightly together than air molecules and therefore in water, there are many more collisions as the bullet moves forward, and the bullet stops much more quickly.
Polyethylene: It is efficient against the friction induced by a bullet`s spin. The bullet is melted and absorbed by this material. It is also light and comfortable to wear. Steel: Is another popular option for hard armor, Steel is still used in the production of body armor today, mostly for ballistic armor plates.
Armor-piercing rounds can penetrate steel body armor. This means, if you`re shot at with those rounds, you were making yourself uncomfortable, hurting your back, and fatiguing the fight in you for no reason because that bullet is getting through.
Its invention is credited to the Celts; the Romans are thought to have adopted their design. Gradually, small additional plates or discs of iron were added to the mail to protect vulnerable areas.
Scientists in Israel have developed the hardest organic material known to man. Tougher than stainless steel and even the previous record holder, bulletproof Kevlar, the transparent material is similar to the beta-amyloid proteins found in patients with memory-robbing Alzheimer`s disease.
Weighing more than eighty-six pounds, it is one of the heaviest field armors known. Although generally conforming to the construction of cuirassier harnesses worn throughout Europe about 1600 to 1640, this example is more characteristic of northern Italian (Milan or Brescia) workmanship.

I have the Intex Sand/Pump pool filter Model SF 20110. It’s been running real great for the last 4 months. However recently it has been tripping the internal overloads and I have found the pump motor to be very hot when I put my hand against it. I have tried several different solutions, such as a level ground platform that was clear of any obstructions, made sure that the motor vents under the motor was clear of anything that would prevent air flow. I used a non electrical type of lubricate on the impeller. When I would turn on the pump the rotor would not turn but only would hum very loudly and then slowly begin to turn. I also noticed that the motor’s rotor shaft would not turn to freely due the tightness around the rotor’s shaft. After using the lubricate the shaft would turn a little easier. I used an amp meter on the incoming voltage line and the motor would run at 4.5 amp. And yet it still overheated and tripped the motor overloads. I can only think that the motor is still not getting enough ventilation. I have check and cleared all the incoming lines and found nothing block the pumps input or output lines. Any suggestion?
ANSWER : I just looking into this issue my self. The pump cools itself by a internal fan, which is run by the motor. Well I took the housing cover off to find out all the fan blades have broken off and were setting in the base of the pump. Once you remove the fan blades from covering the air intake, it might be fine. I will find out my self once summer gets here.

I have purchased three 750-watt power inverters in the last three weeks. They have all failed to work on the second or third use. The first two were the same brand. I replaced an old one that ran for several years. I am using it to run a 4.7 amp 120-volt vacuum cleaner motor that pumps up my air dock. I have it connected directly with marine cable to one of the boat batteries. The battery outputs about 12.8 volts DC. The fuses don?t blow, just No Output. I am using a three-wire 120-volt extension cord and am, wired neutral, hot and ground to the AC motor vial an on/off switch. The motor works fine when I run house power with an extension cord from the dock next to me. Could I be, just unlucky with new inverters and need to buy a forth one?
ANSWER : The problem may be that the inverter is undersized for the load. Is the 4.7 Amp rating the motor peak draw or the nominal one. What I mean is that it takes many times more power to start start the motor than when the motor is running. Typically it is 3 to 7 times more amps to start the motor than when it is running. It could be that starting the vacumm cleaner is stressing the inverter and it is causing it to fail prematurely. If you can find out the locked rotor current draw of the motor, the that would be the mininum size of the inverter.

Also, the type of inverter will make a difference on how the motor operates. A modified sine wave will make the motor run hotter than a pure sine wave inverter. Hope this helps.

I bought the Knoxx adjustable stock for my mossberg 500. The forend that comes with it is realy nice and Ide like to use it, but the end nut will not reach the threads. Do i need to buy a new adapter nut that is longer to secure my forend ? I saw one for sale by houge but wasnt sure if that would work on the knoxx forend ?? I realy like the forend sent by knoxx, would be a shame not to use it. What a waste to give that nice piece away and not give the adapter to use it ?? Thanks Noel
ANSWER : That forearm is designed for the 7 5/8″ slide action tube. I’m guessing yours is the 6 1/2″ slide action tube. Take the forearm off your tube and measure it with a ruler. From the very back edge of the action bar collar….that round part the bars are pinned to….all the way to the front edge of the threads. If yours is a 6 1/2″, the Hogue adapter won’t work. You’ll need to buy a new slide action tube. That Hogue adapter is meant to let you use the Hogue rubber coated forearm on your standard sized tube….the Hogue rubber forearm is a hair longer than the standard tube. It won’t give you the length to make up the entire shorter tube length. If you’re handy with a dremel, you could go adapter plus a bit of careful cutting but I won’t suggest you do it if you aren’t certain of your skills.

We have had this treadmill for a number of years and had not been using it much in past year. We now wish to begin using it again but am wondering if I should oil it. Need to know type of oil and locations on treadmill where this should be done
ANSWER : Hi Bernard
well this will depend on what model it is, is it electric? or is it just a friction type? if it is a friction type, a little wd40 just around the bearings should loosen it up a bit try not to get any on the underside of the belt as this could make it slip on the rollers, but if it is electrical, there is no need to lube it at all as these have heavy duty sealed bearings in which are lubricated inside, so really there isn’t much to really do to them or it should i say, hope this helps please vote and rate tanks

The Bike Technicians Tactic Phase1 An electrical inspection on the bike should produce results. First, the bike battery powers the entire lightening systems mentionable as ignition, meter readings, head lamps, signal indicators. However, the battery provides the power supply to several entities though also significant is the fuse box containing circuit protection coils. Inserting the bike key into the ignition to perform start mode displays the capacity power circuits. A charged battery should display an indication in the meter reading area also known as bike dashboard grading. A malfunctioning start mode on inserting key in ignition may be traceable several locations on the electrical circuits. Attempting to repair the electrical power of the bike usually requires batter power power test kit. The test kit ascertains the battery power making possible progress to the remaining electrical circuits. Test kit also ascertains the fuse box circuit functionality either with fuses still intact or extracted allowing for the next progress level. An observation tour of the bikes electrical wiring kits from battery hold through fuse box compartments to each lightening display area either headlamps, indicators, and meter reading should produce results of any visible damages that may require repairs after the electrical inspection has been performed. Once any faults were observed on the electrical channels, repair mode is the next level. A dull battery either may have been depleted completely of durational capacity requiring another for replacement. Alternately, a depleted power supply due to prolonged storage may require charge functionalities. Usually, a device capacapble of restoring a battery of electrolytes is resorted for charger ability. The type of battery may require constuents either liquid cathode replenishment in the battery entrapment area prior to charging feature is assumed with electrolyte machine. Once the battery has regained full functionality makes way the next repair task. The fuse box may have simply required replacement fuses either as missing or burnt out. A fuse box usually contains additional spare for replacement functionalities. An alternate arrangement at acquiring fuses on the auto mart may replace the burnt devices. The next electrical task is wiring fixtures achievable by mending broken cords with appropriate electrician’s tapes else malfunctions may remain. Alternately, a worn-out electrical wire is replaceable by acquiring the entire extension lengthwise between significant areas. The last remaining electrical units are lightening indicators consisting of bulbs or luminescent displays reflectors. Observe the blub areas either by loosening covers to inspect for observable burnouts else the entire electrical circuitry is ready for functionality observations with separate entities. Engine Technicians Tactic PHASE 2 A bike engine inspection includes observation for indications of malfunction. Any fluid residue is indication of problem areas. Where oil leaks usually requires engine block inspections. A bike engine consists of an entrapment compartment where mechanical combustion takes place. First, the entire observable block consists of an external coating known as engine bloc housing internal component of pistons, rings, and fastens known as cylinder heads. A bike engine has every component embedded within requiring technical expertise to achieve an inspection. Once deciding on the engine task requirements, acquire a tool box with the appropriate componements as first requirement before engine works is commence able. Second, the bike may require an area environment as workshop requirement to attain engine inspections. Third, bike engine are least bulky compared with vehicle engines however assistance would complement the inspection phase. Prior to inspecting the bike engine, a strap mechanism has to be assumed to achieve expert maneuverability also as safe precaution. Unless parts hinder maneuverability at engine locations, the only removable components should be the engine. First, start with disjointing the spark plug cables to acquire accessibility to plugs imbedded on the cylinder heads. The plugs require tools to loosen thereby exposing the combustible area. Once the spark plugs are exposed, two alternatives are likely. First, a spark plug may have gathered rust residue only requiring cleaning to attain regular capacity. The pin area of the spark plug may have been twisted due to overheating and slight melting dislocation. Usually cleaning the residue from old plugs may simply expose the ignitable capacities. However, an observation of twisted plug pin may require twisting back in place to achieve full ignitability once bike engine starts. A bike engine bloc has the pistons as combustibles or blasters of fuel gasoline. The rings perform as strap fasteners whenever the pistons move about combustibility. Usually, the engine entrapment components would have collected residue requiring clearing. Also, pistons together with rings may require replacements either as worn-out due to prolongs tasks or overexerted biker features.
