ASVAB Practice Test Questions and Answers
2022/2023| Verified Answers
1. An induction clutch works by✔✔ magnetism
2.If a first class lever with a resistance arm measuring 2 feet and an effort
arm measuring 8 feet are being used, what's the mechanical advantage?
✔✔ Length of Effort Arm ÷ Length of Resistance Arm. MA = 8 ÷ 2 = 4
3. The force produced when a boxer's hand hits a heavy bag and
"bounces" off it is called✔✔ recoil
4. If Gear 1 has 25 teeth and Gear 2 has 15 teeth, how many revolutions
does Gear 2 make for every 10 revolutions Gear 1 makes?✔✔ r = DR/d,
r=16.6666
5. Springs used in machines are usually made of✔✔ steel
6. A clutch is a type of✔✔ coupling
1/4
, 7. A single block-and-fall is called a✔✔ runner
8.The mechanical advantage of the block-and-tackle arrangement shown
be- low is✔✔ 2. Because this block-and-tackle arrangement merely
changes the direction of the pull, it has a mechanical advantage of
only 2.
9. If a house key, a wooden spoon, a plastic hanger, and a wool jacket are
all the same temperature, which one feels the coldest?✔✔ The key will
feel coldest because metal is a better conductor than the other
materials
10.A way to determine the amount of power being used is?✔✔ The
formula for determining power is Power = Work ÷ Time.
11.A wood tool, a silver tool, and a steel tool are placed in boiling water
for cleaning. Which tool gets the hottest?✔✔ Silver is the best
conductor, so it becomes hottest
12.If an alternator overcharges the battery, a likely explanation is✔✔ The
voltage regulator isn't working properly
