Question 1

On a graphic arithmetic chart, a line rises steeply between two points. What does this steep slope indicate?

Accepted Answer

A rapid rate of change between those values

Answer

A steeper slope on a graph represents a faster rate of change between the plotted points.

Question 2

Two gears mesh together. The driver gear has 20 teeth and the driven gear has 40 teeth. If the driver turns at 100 RPM, how fast does the driven gear turn?

Accepted Answer

50 RPM

Answer

A larger driven gear turns slower in proportion to the tooth ratio, so 100 × (20/40) = 50 RPM.

Question 3

In a series electrical circuit, what happens to the total resistance as more resistors are added?

Accepted Answer

It increases

Answer

Resistances in series add together, so total resistance increases with each added resistor.

Question 4

A worker reads a procedure stating to 'de-energize and verify zero voltage before contact.' What is the primary purpose of this step?

Accepted Answer

To ensure worker safety from electrical shock

Answer

Verifying zero voltage confirms the circuit is safe to touch, preventing electrical shock.

Question 5

If a pulley system uses two supporting rope segments to lift a load, how does the effort needed compare to lifting it directly?

Accepted Answer

About half the effort

Answer

A two-segment pulley provides a mechanical advantage of about two, halving the required effort.
