Ramsay Test Sample 2 — Questions and Answers
Question 1: A gear with 20 teeth drives a gear with 40 teeth. If the small gear turns at 100 RPM, how fast does the large gear turn?
- 50 RPM (Correct answer)
- 100 RPM
- 200 RPM
- 25 RPM
Correct answer: 50 RPM
A gear with twice the teeth turns at half the speed, so 100 RPM becomes 50 RPM.
Question 2: Which tool is best for measuring the inside diameter of a pipe accurately?
- Inside caliper (Correct answer)
- Tape measure
- Protractor
- Feeler gauge
Correct answer: Inside caliper
An inside caliper is designed to measure internal dimensions like a pipe's bore.
Question 3: In an electrical circuit, what does increasing resistance do to current if voltage stays constant?
- Decreases current (Correct answer)
- Increases current
- No change
- Doubles current
Correct answer: Decreases current
By Ohm's law, current equals voltage divided by resistance, so higher resistance lowers current.
Question 4: A first-class lever has the fulcrum located where?
- Between the effort and the load (Correct answer)
- At the load end
- At the effort end
- Outside the lever
Correct answer: Between the effort and the load
A first-class lever places the fulcrum between the effort and the load, like a seesaw.
Question 5: What is the primary purpose of a flywheel on an engine?
- Store rotational energy and smooth output (Correct answer)
- Cool the engine
- Filter the oil
- Increase voltage
Correct answer: Store rotational energy and smooth output
A flywheel stores rotational energy to smooth out engine power delivery between strokes.
Question 6: Which fastener requires a matching internal thread to hold?
- Bolt (Correct answer)
- Rivet
- Nail
- Cotter pin
Correct answer: Bolt
A bolt threads into a nut or tapped hole that has matching internal threads.
Question 7: If a pump delivers water at a higher elevation, what mainly increases?
- Required head pressure (Correct answer)
- Water temperature
- Pipe color
- Electrical frequency
Correct answer: Required head pressure
Lifting water higher requires more head pressure to overcome the increased elevation.
