EEI TECH EEI Tech Spatial Ability 2 — Questions and Answers
Question 1: Looking at a schematic, a switch is shown as an open gap in a circuit line. What does this symbol represent?
- A closed circuit
- An open (off) switch (Correct answer)
- A resistor
- A capacitor
Correct answer: An open (off) switch
An open gap in a circuit line on a schematic represents an open (off) switch.
Question 2: If a bolt viewed from the front shows a hexagonal head, what shape would the head appear if viewed from the end (top)?
- Circle
- Square
- Hexagon (Correct answer)
- Rectangle
Correct answer: Hexagon
The bolt head is hexagonal, so looking directly down the shaft still shows the hexagonal shape.
Question 3: On a wiring diagram, two parallel horizontal lines represent:
- A switch
- A battery or capacitor (Correct answer)
- A fuse
- A ground
Correct answer: A battery or capacitor
Two parallel lines is the standard schematic symbol for a battery or capacitor.
Question 4: A flat piece of sheet metal is bent 90° along its center. Viewed from the side, what shape does it form?
- Straight line
- L-shape (Correct answer)
- U-shape
- Triangle
Correct answer: L-shape
A single 90° bend along the center creates an L-shaped profile.
Question 5: A pulley system has a 10-inch drive pulley connected by belt to a 5-inch driven pulley. If the drive pulley turns at 200 RPM, how fast does the driven pulley turn?
- 100 RPM
- 200 RPM
- 300 RPM
- 400 RPM (Correct answer)
Correct answer: 400 RPM
Speed ratio = drive diameter / driven diameter = 10/5 = 2; so 200 × 2 = 400 RPM.
Question 6: A cylindrical pipe is cut at a 45° angle. What shape is the resulting cross-section?
- Circle
- Rectangle
- Ellipse (oval) (Correct answer)
- Triangle
Correct answer: Ellipse (oval)
Cutting a cylinder at an angle produces an elliptical (oval) cross-section.
