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. :

Once the pitch has been thrown you may remove your foot to reset the machine. This will also be the piece you adjust to change the pitch speed. For 32 mph it should be set to 5. For 34 mph it is moved up to 6 and for 37 mph it is moved to 7.
Pitching Velocity Formula

To calculate pitching velocity, divide the pitching distance by time.

Commercial batting cages pitch with several different speeds, which can range from 30 miles (48 km) (for softball) to 90 miles (140 km) per hour.
The perfect batting-practice pitcher throws everything over the plate around 50-60 miles per hour. Some coaches do have a talent for consistently repeating their mechanics to make this possible.
Variable speed control up to 100 mph for baseball and 90 mph for softball. Built in transport wheels and quick release legs for quick set up and easy storage.
11 And 12-Year-Olds

Pitchers in this age range are playing in the Majors division in Little League. The average fastball is between 50-60 mph. Although at this age the players may begin to reach puberty, and for that reason, it is not unusual to see a pitcher throwing around 70 mph.

A pitcher`s Spin Rate represents the rate of spin on a baseball after it is released. It is measured in revolutions per minute. The amount of spin on a pitch changes its trajectory. The same pitch thrown at the same Velocity will end up in a different place depending on how much it spins.
Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time.
(Distance from hitter) x (simulated velocity) / (actual pitching distance). For instance if you play in a league with 54 foot mounds and you are doing batting practice from 40 feet, and you`d like to simulate 65 mph, you would have 40 ft x 65mph / 54 ft = 48.15mph.
“Power pitchers,” such as former American major leaguers Nolan Ryan and Roger Clemens, rely on speed to prevent the ball from being hit and have thrown fastballs at speeds of 95–105 miles per hour (153–169 km/h) (officially) and up to 108.1 miles per hour (174.0 km/h) (unofficially).
Velocity Myth #2: “I Throw 90”

Despite it being more common than ever, still, very few pitchers can do this. On the average Division-I baseball team, each team usually has 4-8 players capable of touching 90mph, though perhaps only 1 or 2 who can average it.

As far as the technology of the time could tell us, Nolan Ryan threw a 100 mph fastball. Randy Johnson was clocked as high as 102. Bob Feller may have hit 104 in his day, although we only have some creative science experiments to rely on for that figure.
Look for a machine with pitch speeds of 90 mph or more, two wheels, dual motors, and a lot of pitching options. Keep weight and portability in mind if you need to move it. Most machines can throw left, right, curveballs, fastballs, and sliders.
Most pitching machines operate on 110vAC/1000 watts. This means that you can plug them into a power source if available, or power them using a generator. If you plan to use a generator, find out what kind the manufacturer recommends before buying.
The average throwing velocity for a 17 year old typically ranges between 70-85 mph, though individual performance can vary greatly due to factors such as physical maturity, training history, and technique.
13-14 years old: 60-70 mph. 15-16 years old: 70-80 mph. High school: 75-85 mph. College/professional: 85-95+ mph.
In 2018, there were 1,320, a nearly sevenfold increase. In 2008, only 11 pitchers averaged 95 mph or higher; in 2018, 74 did.
Use explosive movements: In order to generate maximum velocity, your body needs to be able to produce a lot of force quickly. To train this quality, make sure to include exercises that involve explosive movements such as plyometrics, medicine ball throws, and Olympic lifting.
Spin rate, or raw spin, measures the overall revolutions per minute (rpm) of a pitched ball by adding together the amount of backspin, topspin, sidespin, and gyroscopic spin (i.e. bullet spin, football spiral, etc.) put on the ball.
Two-seam fastballs/sinkers (MLB average spin rate ≈2150 rpms) should have spin efficiencies between 75-100%; this range is wide primarily due to the fact that different efficiencies work best with different spin directions, arm slots, and grip/feel.
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object`s movement. Put another way, speed is a scalar value, while velocity is a vector.
The basic unit or the S.I. unit of speed is meter per second. This means that to cover a distance of 1 meter, the time required is 1 second.
If you`re going 80 mph, it will take you 1 hour to go 80 miles. The abbreviation “mph“ means miles per hour. Therefore, 80 mph means 80 miles per hour. Hence if someone is traveling at 80 miles per hour, it means that they travel 80 miles every 1 hour, so this tells us that it would take them 1 hour to go 80 miles.
80 mph = Approx. 0.50 sec.

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.

TC5000 and after extended use I smell burning and upon removing the belt cover and drive belt I felt of the motor on the motor side of the drive pulley and it was ”red-hot”, obviously the source of the smell of the burning. The motor spins freely without any rubbing noise. The drive pulley (motor side) and the tread pulley appear to be alligned. One curious thing is that the threaded motor output shaft is recessed about 3/8” from the outside edge of the pulley. Could it be the bearing on the pulley side of the motor? I am dumbfounded as to what the solution might be. Note that I could not enter the exact product as my model seemed to be invalid. My model is the TC5000. Thanks [email protected]
ANSWER : Just because it spins freely doesnt mean it cant have a shorted winding. Id send it back where it came from or at least replace the motor.

My daughter has a sweet pea scooter that had been blowing fuses and the motor got hot. Im sure the motor is shot. but my question is can anyone tell me if the motor would be the only thing I need to c
ANSWER : Find out whether it is 6 volts or 12 volts and there should be two wires that feed the motor either cut or splice and attach another set of wires with fuse in the line (simular to jumper cables) raise the back tire so it does not touch the ground and place jump wires to the negative and positive of the battery.If the motor moves in either direction without blowing the fuse the motor is good if not then its bad. Uses the same amperage fuse

Motor was running great, but it died slowly and never start again
ANSWER : Check to see if you have a spark -then check if you are still getting fuel-and how old is the fuel-because it is recommended ,an im assuming its a 2 stroke motor,that the fuel should be replace with a fresh 2 stroke mixture every couple of months as the mixture jellyfies and sludges up the carb etc-try those first

2002 Merc. outboard overheating
ANSWER : It sounds like your lower unit pump is going out
hook it to a fresh water hose and run the engine and see if more water comes out of the exaust if it is more then i would replace the lower unit pump check and see if the screens on the lower unit are plug up with seaweed and clean them that would restric the flow of water

I have a 1997 motor guide wireless 24volt Big Water trolling motor. hooked it up to the batteries and put in a new 9volt battery in the foot pedal. the lights come on on top of the motor head and the foot pedal beeps, but the prop doesnt turn or spin (like there is no power to the bottom of the motor) any suggestions to what the problem is or how to fix it? (just bought the motor from a lady who’s husband died. dont have any manuals)
ANSWER : Hello there, as you said the power does not get to the bottom of the motor. The motor could be faulty or just completely bad. First you have to determine that the motor is good until you can determine this it is quite impossible to determine if there can be any fix. Take out the motor and try to power it on its own if it works fine then the problem is not from the motor but most likely the problem is from the motor. Let me know what your findings are. Hoping to hear from you soon.
Thank you for visiting FixYa.

I have a 1991 Yamaha 250 outboard motor. I can connect the harness from the control box to the motor harness, put the motor in nuetral, and the motor will turn over but it will not start. I can disconnect the conrol box from the motor, jump it direct from the battery, and it will start. What might be the problem? I even bought a new control box but still have the same problem.

Thank you,
Dean Youngstrand

ANSWER : I would check for power coming off of the ignition switch. The ignition switch is what sends power to the control box to the coil. You can also check for power on your coil. But I would bet that it is your ignition switch.
