  1. A hoist rope stretches 0.125 inch under load. Express this as a fraction in lowest terms.

    Answer: 1/8 inch

    0.125 = 125/1000 = 1/8 in lowest terms.

  2. Three shims measure 3/16, 5/16, and 7/16 inch. What is their total thickness?

    Answer: 15/16 inch

    3/16 + 5/16 + 7/16 = 15/16 inch.

  3. An inspection takes 0.3 hours per floor and a building has 15 floors. How many hours total?

    Answer: 4.5 hours

    0.3 × 15 = 4.5 hours.

  4. A pulley has a diameter of 2 1/4 inches. Its radius is:

    Answer: 1 1/8 inches

    Radius = 2 1/4 ÷ 2 = 9/4 ÷ 2 = 9/8 = 1 1/8 inches.

  5. A lubricant costs $3.60 per quart. How much do 2.5 quarts cost?

    Answer: $9.00

    $3.60 × 2.5 = $9.00.

  6. A wire rope has a safe working load of 4/5 of its breaking strength. If breaking strength is 5,000 lbs, the safe load is:

    Answer: 4,000 lbs

    4/5 × 5,000 = 4,000 lbs.

  7. A shaft is machined down from 2.500 inches to 2.375 inches. How much material was removed?
