What is Torque?

The rotating force that a tool or an object like a motor exerts is measured in torque. The distance between the point of application and the axis of rotation is multiplied by the force employed to create it. Typically, torque is expressed in Newton metres (Nm) or foot-pounds (ft-lbs).

Think of a motor that is turning a wheel as an illustration. The wheel rotates as a result of the motor exerting force on it. The strength of the force being applied and the distance between the point of application (the motor) and the axis of rotation defines how much torque the motor creates (the centre of the wheel).

 If the force is increased or the distance is increased, the torque will also increase.

Torque is an important concept in mechanics and is used to describe the rotational force of an object. It is often used in the design of machines, such as motors and gears, to ensure that they have sufficient power to perform their intended functions. Torque is also an important consideration in the operation of vehicles, as it determines their acceleration and ability to climb hills and tow loads.

The two types of torque are static and dynamic. A torque that does not result in an angular acceleration is called static. Here are a few instances of static torque:

• Static torque can be applied in a number of ways, like pushing a closed door while it is still in place and pedalling a bicycle at a constant speed when there is no acceleration.
• As a racing vehicle accelerates off the line, the drive shaft must accelerate the wheels in an angular direction since the vehicle is moving quickly along the track.
