As shown in the figure below, a bicycle wheel is at rest against a curb. If the wheel has a radius R, mass M, and is at rest against a curb of height h = 0.314R, determine the minimum horizontal force F (in terms of M and g) that must be applied to the axle to make the wheel start to rise up over the step. (Do not substitute numerical values; use variables only.) F= M Additional Materials
