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 = 0.585R, 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= 2.609 Determine a convenient point about which to determine the torques. Since we need to determine the torque, before starting the problem, see if you can write an expression for the torque in terms of the force producing the torque and the perpendicular distance between the line of action of this force and the point about which we are determining the torques. See if you can apply the condition for rotational equilibrium that will allow you to determine the force Fin terms of known quantities. Some basic trigonometry might be needed in order to determine all distances needed. м
