Derive an expression for the workdone by a torque?

Explanation:

Work done by torque = magnitude of force * perpendicular distance between the point of action and point(axis) of rotation.

Work done by torque = magnitude of force * perpendicular distance between the point of action and point(axis) of rotation.

Explanation:

We can also write this as :-

W = F x d

where,

W->Work Done

F->Force

d->displacement

your answer would be fusion

this could be newton#'s law of cooling. the cooling curve is exponential
