An elevator hoistway is 8 feet wide and 6 feet deep. If a car platform must maintain a 3-inch clearance on each side, what is the maximum platform width?

Answer: 7 feet 6 inches

3 inches clearance on each side = 6 inches total subtracted from 8 feet, leaving 7 feet 6 inches.

A spiral staircase turns 270 degrees over 12 steps. How many degrees does each step represent?

A rectangular elevator pit is 4 feet deep, 6 feet wide, and 5 feet long. What is its volume in cubic feet?

Answer: 120 cubic feet

Volume = length × width × depth = 5 × 6 × 4 = 120 cubic feet.

If you rotate a capital letter 'T' by 180 degrees, which letter does it most resemble?

Answer: ⊥ (an upside-down T)

Rotating a T by 180 degrees produces an inverted T shape, which looks like the perpendicular symbol.

A guide rail bracket extends 14 inches from the hoistway wall to the rail centerline. If two parallel rails are centered 42 inches apart, how far apart are the two walls they attach to?

Answer: 70 inches

Each bracket adds 14 inches from its wall, so total wall-to-wall = 42 + 14 + 14 = 70 inches.

Which cross-section shape would result from cutting a cylinder horizontally (perpendicular to its axis)?

Answer: Circle

A horizontal cut perpendicular to a cylinder's vertical axis produces a perfect circle.
