Draw a free-body diagram for the motorcycle of weight W shown in Figure P2.6D for (a) rear wheel braking only, (b) front wheel braking only, and (c) front and rear wheel braking. Also, determine the magnitudes of the forces exerted by the roadway on the two tires during braking for the above cases. The motorcycle has a wheel base of length L. The center of gravity is a distance c forward of the rear axle and a distance of h above the road. The coefficient of friction between the pavement and the tires is µ.
