EIAT EIAT Spatial Reasoning and Visualization 4 — Questions and Answers
Question 1: 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?
- 7 feet 6 inches (Correct answer)
- 7 feet 9 inches
- 7 feet 3 inches
- 7 feet
Correct answer: 7 feet 6 inches
3 inches clearance on each side = 6 inches total subtracted from 8 feet, leaving 7 feet 6 inches.
Question 2: A spiral staircase turns 270 degrees over 12 steps. How many degrees does each step represent?
- 22.5 degrees (Correct answer)
- 25 degrees
- 30 degrees
- 20 degrees
Correct answer: 22.5 degrees
270 degrees divided by 12 steps equals 22.5 degrees per step.
Question 3: When looking at a floor plan, a dashed line inside a room typically represents:
- An overhead feature or object above the cut plane (Correct answer)
- A wall that will be demolished
- A sliding door track
- An underground utility line
Correct answer: An overhead feature or object above the cut plane
In architectural drawings, dashed lines indicate features located above the horizontal cut plane of the floor plan.
Question 4: A rectangular elevator pit is 4 feet deep, 6 feet wide, and 5 feet long. What is its volume in cubic feet?
- 120 cubic feet (Correct answer)
- 96 cubic feet
- 110 cubic feet
- 140 cubic feet
Correct answer: 120 cubic feet
Volume = length × width × depth = 5 × 6 × 4 = 120 cubic feet.
Question 5: If you rotate a capital letter 'T' by 180 degrees, which letter does it most resemble?
- ⊥ (an upside-down T) (Correct answer)
- L
- Y
- I
Correct answer: ⊥ (an upside-down T)
Rotating a T by 180 degrees produces an inverted T shape, which looks like the perpendicular symbol.
Question 6: 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?
- 70 inches (Correct answer)
- 56 inches
- 84 inches
- 28 inches
Correct answer: 70 inches
Each bracket adds 14 inches from its wall, so total wall-to-wall = 42 + 14 + 14 = 70 inches.
Question 7: Which cross-section shape would result from cutting a cylinder horizontally (perpendicular to its axis)?
- Circle (Correct answer)
- Ellipse
- Rectangle
- Oval
Correct answer: Circle
A horizontal cut perpendicular to a cylinder's vertical axis produces a perfect circle.
An elevator hoistway is 8 feet wide and 6 feet deep.
