Question

What Torque means?

Answer 1

1. Torque is the measure of the force that can cause an object to rotate about an axis.
2. Force is what causes an object to accelerate in linear kinematics.
3. Similarly, torque is what causes an angular acceleration.
4. Hence, torque can be defined as the rotational equivalent of linear force.
5. The straight line about which the object rotates is called the axis of rotation.
6. In physics, torque is simply the tendency of a force to turn or twist. Different terminologies such as moment or moment of force are interchangeably used to describe torque. The distance of the point of application of force from the axis of rotation is sometimes called the moment arm or lever arm.
