  1. A hydraulic jack raises a car at 0.25 feet per second. How many inches per minute does it rise?

    Answer: 180 in/min

    0.25 ft/s × 12 in/ft × 60 s/min = 180 in/min.

  2. An overhead clearance of 14 feet 6 inches must be recorded in decimal feet. What is the correct value?

    Answer: 14.5 ft

    6 inches = 6/12 = 0.5 feet, so 14 ft 6 in = 14.5 feet.

  3. A car operating at 200 fpm must be expressed in meters per minute. (1 ft = 0.3048 m)

    Answer: 60.96 m/min

    200 ft/min × 0.3048 m/ft = 60.96 m/min.

  4. A wiring conduit must span 7 yards. How many feet of conduit is needed?

    Answer: 21 ft

    7 yards × 3 ft/yard = 21 feet.

  5. A traction elevator counterweight displacement is measured at 2,400 cubic centimeters. How many liters is that?

    Answer: 2.4 L

    2,400 cm³ ÷ 1,000 cm³/L = 2.4 liters.

  6. A roped hydraulic system uses 30 psi of pressure. Convert this to kPa. (1 psi ≈ 6.895 kPa)

    Answer: 206.85 kPa

    30 psi × 6.895 kPa/psi = 206.85 kPa.

  7. A hoist drum makes 5.5 revolutions per rope pull. If the drum diameter is 24 inches, how many feet of rope is wound per pull?

    Answer: 34.56 ft

    Circumference = π × 24 ≈ 75.36 in; 5.5 × 75.36 = 414.5 in ÷ 12 = 34.56 ft.
