The perpendicular distance from the axis to the line of the force is called the:
ALoaded arm
BLever arm
CLevel arm
DLinear arm
Answer & Solution
Correct answer: B. Lever arm
1. Only the perpendicular part of the distance produces turning.
2. That length multiplies the force to give torque.
3. It is the lever arm.
