Solution of task 2.6.4 from the collection of Kepe OE

2.6.4
A horizontal force F is applied to a homogeneous roller with a weight of 2 kN. Determine the largest modulus of force F at which the roller does not slip and roll, if the coefficient of rolling friction? = 0,006 m, coefficient of sliding friction f = 0,2, radius R = 0,6 m, size OA = 0,4 m. (Answer 12,0)
