What is Torque?

Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics. Similarly, torque is what causes an angular acceleration. Hence, torque can be defined as the rotational equivalent of linear force. The point where the object rotates is called the axis of rotation. 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.

Types of Torque

Torque can be either be static or dynamic. Static torque is a torque that does not produce an angular acceleration. A few examples of static torque are as follows:

How is Torque Calculated?

A simple way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force.

A simple way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force.Now, from the above observation, we conclude that torque produced depends on the magnitude of the force and the perpendicular distance between the point about which torque is calculated and the point of application of force. So mathematically torque is represented as:

$\boxed{τ = F.r. sinθ }$

Measurement of Torque

The unit of torque is Newton–meter (N-m). The above equation can be represented as the vector product of force and position vector.

The unit of torque is Newton–meter (N-m). The above equation can be represented as the vector product of force and position vector.τ = r x F

The unit of torque is Newton–meter (N-m). The above equation can be represented as the vector product of force and position vector.τ = r x FSo as it is a vector product hence torque also must be a vector. Using vector product notations we can find the direction of torque. We will consider an example to see how to calculate torque.
