ASVAB TEST 2026/2027 BRAND NEW ACTUAL EXAM WITH
ANSWERS | GRADED A+
An induction clutch works by - ANSWER magnetism
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? - ANSWER Length of Effort Arm ÷ Length of Resistance
Arm. MA = 8 ÷ 2 = 4
The force produced when a boxer's hand hits a heavy bag and "bounces" off it is called - ANSWER
recoil
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? - ANSWER r = DR/d, r=16.6666
Springs used in machines are usually made of - ANSWER steel
A clutch is a type of - ANSWER coupling
A single block-and-fall is called a - ANSWER runner
The mechanical advantage of the block-and-tackle arrangement shown below is - ANSWER 2.
Because this block-and-tackle arrangement merely changes the direction of the pull, it has a
mechanical advantage of only 2.
If a house key, a wooden spoon, a plastic hanger, and a wool jacket are all the same temperature,
which one feels the coldest? - ANSWER The key will feel coldest because metal is a better conductor
than the other materials
A way to determine the amount of power being used is? - ANSWER The formula for determining
power is Power = Work ÷ Time.
A wood tool, a silver tool, and a steel tool are placed in boiling water for cleaning. Which tool gets
the hottest? - ANSWER Silver is the best conductor, so it becomes hottest
, If an alternator overcharges the battery, a likely explanation is - ANSWER The voltage regulator isn't
working properly
A primary advantage of the electronic ignition system over conventional ignition systems is -
ANSWER The electronic ignition system provides a higher voltage
The primary purpose of piston rings is to - ANSWER seal the combustion chamber and allow the
pistons to move freely
Connecting rods connect the piston to the - ANSWER crankshaft
In an overhead valve system (OHV), what mechanism opens and closes the valves? - ANSWER rocker
arms
The difference between a single-acting and an opposed piston engine is - ANSWER Single-acting
piston engines have one piston per cylinder and opposed piston engines have two
A car equipped with limited-slip differential - ANSWER transfers the most driving force to the wheel
with the greatest amount of traction
Soft brake-pedal movement can be caused by - ANSWER air in the hydraulic brake system
The safest way to make a hole in sheet metal is to - ANSWER punch it using a metal punch
Nail sets are used to - ANSWER set nails below the surface of the wood
A ripsaw cuts - ANSWER with the grain of the wood
A bucking bar is used to - ANSWER drive rivets
Washers that have teeth all around the circumference to prevent them from slipping are called -
ANSWER shakeproof washers
