Two blocks are supported by a pulley along an incline as shown. The lower block B has a weight of 30 lbs and the higher block A has a weight of 20 lbs. Assume that there is friction between the blocks with H3 = 0.15 and assume no friction between block B and the incline. Determine the angle z for which motion is impending. 2016 30lb Tension in block A as a function of z can be written as TA Tension in block Bas a function of z can be written as Tg Thus, impending motion is at r = degrees.
