  1. A movable pulley is attached to a load weighing 300 lb. Ignoring friction, how much force is needed to lift it?

    Answer: 150 lb

    A movable pulley provides a mechanical advantage of 2, so the required effort is 300 ÷ 2 = 150 lb.

  2. Gear X (20 teeth) drives Gear Y (60 teeth). If Gear X makes 90 RPM, what is the torque relationship between the gears?

    Answer: Gear Y has more torque than Gear X

    When a smaller gear drives a larger gear, speed decreases and torque increases in the larger gear by the same ratio.

  3. A crowbar is being used to pry open a crate. The fulcrum is near the crate (load). What class lever is this?

    Answer: Class 1

    A crowbar with the fulcrum between the effort and load is a Class 1 lever, like a seesaw.

  4. A compound pulley system requires 50 lb of effort to lift a 200-lb load. What is the mechanical advantage?

    Answer: 4

    Mechanical advantage = Load ÷ Effort = 200 ÷ 50 = 4.

  5. Which type of lever is a wheelbarrow an example of?

    Answer: Class 2

    A wheelbarrow is a Class 2 lever because the load is between the fulcrum (wheel) and the effort (handles).

  6. Two gears rotate in mesh. Gear A turns clockwise. In which direction does Gear B turn?

    Answer: Counterclockwise

    When two gears are directly meshed, they always rotate in opposite directions.
