23. 

If the rim of the wheel and its hub maintain contact with the three stationary tracks as the wheel rolls, it is neccessary that slipping occurs at the hub A if no slipping occurs at B. Under these conditions, what is the speed at A if the wheel has an angular velocity ?

[A]. vA = (r2-r1)
[B]. vA = r1
[C]. vA = (r2-r1)
[D]. vA = r1

Answer: Option A
