Question

Perpendicular distance between the axis of rotation and line of action of force is called: ​

Answer 1

Answer:

What is relevant is the perpendicular distance from the axis of rotation and the line of action. This perpendicular distance is called the lever arm, l

hope will be helpful ☺️

Answer 2

Concept introduction:

The "moment arm" is the distance, measured perpendicularly, between the force F's "line of action" and its axis of rotation (or pivot) (sometime, the "lever arm"). From the rotational axis to the point of the force F, draw a vector r.

Explanation:

Given that, Perpendicular distance between the axis of rotation and line of action of force.

We have to find, what is known as perpendicular distance between the axis of rotation and line of action of force.

According to the question,

Perpendicular distance between the axis of rotation and line of action of force is called lever arm.

Final Answer:

Lever arm is the perpendicular distance between the axis of rotation and line of action of force.
