  1. An elevator machine room drawing shows a scale of 1/4 inch = 1 foot. A machine measures 3.5 inches on the drawing. What is its actual length?

    Answer: 14 feet

    At 1/4 inch per foot, divide the drawing measurement by 0.25: 3.5 ÷ 0.25 = 14 feet.

  2. A wire rope makes two full wraps around a sheave. How many degrees of total rotation does this represent?

    Answer: 720 degrees

    One full wrap equals 360 degrees, so two full wraps equal 720 degrees.

  3. Looking at a front elevation drawing of an elevator door, the center-opening door panels are shown in the closed position. Where would both panels be located when fully open?

    Answer: Each panel slides to the opposite side walls of the door opening

    Center-opening doors have two panels that slide away from each other toward opposite jambs when opening.

  4. A counterweight assembly is shown in a hoistway cross-section. If the car is positioned on the left side of the hoistway, where is the counterweight typically located?

    Answer: On the right side or rear of the hoistway

    The counterweight travels in a separate guide rail path offset from the car, typically on the opposite or rear side of the hoistway.

  5. A net is unfolded to form a 3D shape with 4 triangular faces and 1 square base. What solid does it form?

    Answer: Square pyramid

    A square base with 4 triangular faces that meet at a point forms a square pyramid.

  6. In a hydraulic elevator diagram, the plunger extends upward into the cylinder. If the cylinder is buried 10 feet into the ground and the plunger stroke is 12 feet, what is the maximum height the car platform rises?

    Answer: 12 feet

    The travel height equals the stroke length of the plunger, which is 12 feet regardless of cylinder burial depth.

  7. An isometric drawing of a hoistway shows three visible faces of a rectangular box. If the top face shows a 4×6 grid and the front face shows a 4×3 grid, what does the side face grid show?

    Answer: 6×3 grid

    The side face shares the depth (6) and height (3) dimensions seen on the top and front faces respectively.
