• ##### Torque Formula (Moment of Inertia and Angular Acceleration)

The wheels of a toy car each have a mass of kg, and radius cm. If the angular acceleration of a wheel is radians/s 2, what is the torque? Answer: The torque can be found using the torque formula, and the moment of inertia of a solid disc. The torque is: τ = Iα. τ = N∙m. The torque applied to one wheel is N∙m.

• ##### 3 Ways to Calculate Torque

Dec 04, 2020 · The magnitude of that rotation is torque (τ), expressed in newtonmeters (N∙m). The most basic way to calculate torque is to multiply the Newtons of force exerted by the meters of distance from the axis. There's also a rotational version of this formula for 3dimensional objects that uses the moment of inertia and angular acceleration.
