ASVAB practice test 1 exam 2022/2023 with 100% correct answers
An induction clutch works by 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? 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 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? r = DR/d, r=16.6666 Springs used in machines are usually made of steel A clutch is a type of coupling A single block-and-fall is called a runner The mechanical advantage of the block-and-tackle arrangement shown below is 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? 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? 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? Silver is the best conductor, so it becomes hottest If an alternator overcharges the battery, a likely explanation is The voltage regulator isn't working properly A primary advantage of the electronic ignition system over conventional ignition systems is The electronic ignition system provides a higher voltage The primary purpose of piston rings is to seal the combustion chamber and allow the pistons to move freely Connecting rods connect the piston to the crankshaft In an overhead valve system (OHV), what mechanism opens and closes the valves? rocker arms The difference between a single-acting and an opposed piston engine is Single-acting piston engines have one piston per cylinder and opposed piston engines have two A car equipped with limited-slip differential transfers the most driving force to the wheel with the greatest amount of traction Soft brake-pedal movement can be caused by air in the hydraulic brake system The safest way to make a hole in sheet metal is to punch it using a metal punch Nail sets are used to set nails below the surface of the wood
