Question 1

A V-belt drive slips when the load is too high. What is the most effective solution?

Accepted Answer

Increase belt tension or install a wider/higher-capacity belt

Answer

Slipping means the belt cannot transmit the required torque; increasing tension or using a higher-capacity belt restores grip.

Question 2

Two pistons in a hydraulic system: piston A has an area of 5 sq in and piston B has an area of 25 sq in. If piston A moves 10 inches, how far does piston B move?

Accepted Answer

2 inches

Answer

Volume is conserved: A_A × d_A = A_B × d_B → 5×10 = 25×d_B → d_B = 2 inches.

Question 3

What does a torque wrench measure?

Accepted Answer

The rotational force applied to a fastener

Answer

A torque wrench measures and limits the rotational force (torque) applied when tightening fasteners to a specified value.

Question 4

In a pulley system, if you pull the rope 6 feet to raise a load 2 feet, what is the mechanical advantage?

Accepted Answer

3

Answer

Mechanical advantage = distance effort moves / distance load moves = 6 ft / 2 ft = 3.

Question 5

A shaft rotates clockwise when viewed from one end. When viewed from the opposite end, it rotates:

Accepted Answer

Counterclockwise

Answer

The rotation direction reverses when you view a shaft from the opposite end, just as a clock face appears to run backwards from behind.
