Consider the yo-yo (of mass M and outer radius R ) shown in the… Consider the yo-yo (of mass M and outer radius R) shown in the figure, where the string is being pulled with a force of magnitude F (F < M g) at an angle ? to the horizontal. The radius of the inner axis is r (so that r < R). Assume that the angle ranges from 0 to p/2, and the coefficient of static friction with the ground is very large.Enter an expression for the critical angle (in radians, between 0 and p / 2) at which the yo-yo will remain motionless. Use ? = r / R to simplify your expression. Calculate this critical angle ?c, in degrees, if the yo-yo has an outer radius of 3.4 cm and an inner radius of 0.81 cm. Math PHY 104
