An induction clutch works by - Correct 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? - Correct 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 - Correct 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? - Correct Answer - r = DR/d, r=16.6666
