  1. Two gears are connected. Gear A has 40 teeth and Gear B has 20 teeth. If Gear A rotates at 30 RPM, how fast does Gear B rotate?

    Answer: 60 RPM

    RPM ratio is inversely proportional to gear teeth: 30 × (40/20) = 60 RPM.

  2. A lever has its fulcrum at the center. A 60 kg weight is placed 2 meters left of the fulcrum. How much force is needed 3 meters to the right to balance it?

    Answer: 40 kg

    Torque balance: 60 × 2 = F × 3; F = 120 ÷ 3 = 40 kg.

  3. Water flows through a pipe at 10 liters per minute. If the pipe splits into two equal branches, how much flows through each branch?

    Answer: 5 liters per minute

    Flow divides equally between two identical branches: 10 ÷ 2 = 5 liters per minute each.

  4. A block and tackle system uses 4 rope segments supporting a load. If the load weighs 200 lbs, approximately how much effort force is needed (ignoring friction)?

    Answer: 50 lbs

    Mechanical advantage of a block and tackle = number of rope segments = 4; effort = 200 ÷ 4 = 50 lbs.

  5. If you look at a clock showing 3:00, and then see its mirror image, what time does the mirror image show?

    Answer: 9:00

    A mirror image of a clock reverses left and right; 3:00 becomes 9:00 in the mirror.

  6. A bolt is tightened by turning it clockwise. To loosen the bolt, which direction do you turn it?

    Answer: Counterclockwise

    Standard bolts follow the righty-tighty, lefty-loosey rule: counterclockwise loosens.
