ASVAB PRACTICE TEST 1 QUESTIONS AND ANSWERS 100% SOLVED…GRADE A+ 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
