The homogeneous body with two small feet and two ideal wheels is at rest on the rough incline. (a) Assume no slippage and determine the maximum value of the angle () for which the body does not overturn about feet A. (b) If µ,s = 0.40, determine the maximum value of the angle () for which the body does not slip. (c) If µ,s = 0.40 and side C of the body now faces up the incline, determine the maximum value of the angle () for which the body does not slip.
