Question

What is the dimension and unit for torque?

Answer 1

Answer:

unit is newton-metre bz torque is similar to work done

Answer 2

Answer:

Force causes accelerations and Torque causes angular accelerations.Torque is proportional to the distance between the rotation axis and the point of application of the force (the point at which the force is applied).

Mathematically, Torque is defined as product of Angular acceleration and Moment of Inertia. Its formula is

Torque = Angular Acceleration X Moment of Inertia

Dimensional Formula of Angular Acceleration = M0L0T-2

Dimensional Formula of Moment of Inertia= M1L2T0

Putting these values in above equation we get

Dimensional Formula of Torque= M1L2T-2

SI unit of Torque is N m
