A cord is wrapped around the inner drum of a wheel and pulled horizontally with a force of 200N. The wheel has a mass of 50 kg and a radius of gyration of 0.07 m. Let ms = 0.20 and mk = 0.15.

(a) Determine the friction force, F at the wheel ground contact point assuming that the wheel rolls without

slipping.

(b) Compare the friction force F found in (a) to Fmax and comment with respect to the rolling without slipping assumption
