✍️ Sample Plant Operator Selection System Test Questions & Answers
1. A pattern sequence shows a shape rotating 90° clockwise each step. If step 1 is an arrow pointing right, what does step 3 show?
Step 1 points right, step 2 points down (90° CW), and step 3 points left (another 90° CW).
2. A shape is reflected across a vertical axis. If the original shows a right-pointing arrow on the left side of a box, what does the reflection show?
Reflection across a vertical axis flips left-to-right and reverses horizontal direction, moving the arrow to the right side and pointing left.
3. Heat flows from a hotter object to a cooler object until:
The Second Law of Thermodynamics states heat naturally flows from high temperature to low temperature until both objects reach the same temperature.
4. If a 100 lb object is lifted using a block-and-tackle system with 4 rope segments supporting the load, approximately how much pull force is required (ignoring friction)?
The mechanical advantage equals the number of rope segments supporting the movable block, so 100 ÷ 4 = 25 lb.
5. A pressure gauge reads 85 psi. If atmospheric pressure is 14.7 psi, what is the absolute pressure?
Absolute pressure = gauge pressure + atmospheric pressure = 85 + 14.7 = 99.7 psi.
6. A sequence shows: square with 1 dot inside → square with 2 dots inside → square with 3 dots inside. What comes next?
The pattern adds one dot inside the square with each step, so the next figure has 4 dots.
