A double-cylinder body of mass m rolls without slipping on a rough horizontal surface. Two equal horizontal forces F act as shown. The outer rolling radius is 3R and $I = 5 m R^{2} /2$ . Determine the direction of friction.

double cylinder with forces and radii

Options:

Answer:

Solution:

Write translation and rotation equations with rolling constraint $a = 3 R α$ .

The required contact force is negative in the +x convention, so friction acts backward.
