  1. A 200 lb crate must be slid up a frictionless inclined plane that is 10 ft long and 2 ft high. What force is required?

    Answer: 40 lb

    Force on an inclined plane = weight × (height/length) = 200 × (2/10) = 40 lb.

  2. A wrench applies 30 lb of force at 1.5 ft from a bolt's center. What is the torque applied to the bolt?

    Answer: 45 ft-lb

    Torque = Force × Distance = 30 lb × 1.5 ft = 45 ft-lb.

  3. A steel rod is 100 inches long at 70°F. If heated to 170°F, it expands. Which statement is correct?

    Answer: It becomes slightly longer

    Metals expand when heated; a 100°F increase causes measurable elongation based on the material's coefficient of thermal expansion.

  4. A drive belt connects two pulleys. The driver pulley is 4 inches in diameter and spins at 600 RPM. The driven pulley is 8 inches in diameter. What is the driven pulley's speed?

    Answer: 300 RPM

    Belt drive speed ratio: output RPM = input RPM × (driver diameter / driven diameter) = 600 × (4/8) = 300 RPM.

  5. Two workers each push a box. Worker A pushes with 80 lb for 10 feet. Worker B pushes with 40 lb for 20 feet. Who does more work?

    Answer: They do equal amounts of work

    Work = Force × Distance; Worker A: 80×10 = 800 ft-lb; Worker B: 40×20 = 800 ft-lb — identical.

  6. A screw has 16 threads per inch. How far does the screw advance into a material with each full turn?

    Answer: 1/16 inch

    Pitch = 1 / threads per inch = 1/16 inch per revolution.

  7. A vehicle traveling around a curve tends to slide outward. This tendency is best resisted by:

    Answer: Tilting (banking) the road surface inward

    Banking a road inward redirects the normal force to provide a centripetal component, countering the outward tendency without relying on friction alone.
