How is torque or moment of force measured ?

A force of 8 N is applied to a body at a distance of 20 cm from the point at which it is pivoted. Calculate the torque or moment of force about the pivot.

How is the work done by a force measured when (i) force is in the direction of displacement, (ii) force is at an angle to the direction of displacement ?

How did you define moment of a force?

How is work done by a force measured when the force : is at an angle of displacement

How is work done by a force measured when the force : is in the direction of displacement.

Give an example for torque or moment of couple.

What do you understand by torque and moment of inertia ? Obtain the relation between torque and moment of inertia for a rigid body.

The rotational analogue of force is moment of force, also called torque.The possibility of falling backward with the ladder is more when you are high upon the ladder than when you just begin a climb. Explain why.

Define moment of force or torque.
