SUMMARY
The equation for torque (T) is defined as T = Iα, where I represents the moment of inertia and α is the angular acceleration. For a solid cylinder, the moment of inertia is I = (1/2) m r²; for a hollow cylinder, it is I = m r²; and for a sphere, it is I = (2/5) m r². These equations are essential for calculating the torque of these shapes as they roll down an incline.
