Question

A sphere is rolling on a rough surface without any slipping at the
point of contact Find the radius of curvature of the trajectory of
the point A when it is at a distance R/2 above the centre of the
sphere

Ved Prakash Lakhera · Accepted Answer

The trajectory of the point A at distance R2, where R is the radius of the sphere is a sinusoidal harmonic wave of amplitude 3R2, on the rough surface

A sphere is rolling on a rough surface without any slipping at the point of contact. Find the radius of curvature of the trajectory of the point A when it is at a distance R/2 above the centre of the sphere.
