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 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 13. A primary advantage of the electronic ignition system over conventional ignition systems is: The electronic ignition system provides a higher voltage 14. The primary purpose of piston rings is to: seal the combustion chamber and allow the pistons to move freely 15. Connecting rods connect the piston to the: crankshaft 16. In an overhead valve system (OHV), what mechanism opens and closes the valves?: rocker arms 17. 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
