Question

A disc of mass M and radius R is placed a rough horizontal surface with its axis horizontal. A light rod of length '2R' is fixed to the disc at point 'A' as shown in figure and a force `3/2` Mg is applied at the other end. If disc starts to roll without slipping the value of "10 × µ_min" where µ_min is minimum coefficient of friction between disc and horizontal surface required for pure rolling is ______.

Answer 1

A disc of mass M and radius R is placed a rough horizontal surface with its axis horizontal. A light rod of length '2R' is fixed to the disc at point 'A' as shown in figure and a force `3/2` Mg is applied at the other end. If disc starts to roll without slipping the value of "10 × µ_min" where µ_min is minimum coefficient of friction between disc and horizontal surface required for pure rolling is 8.
