Extracted text: Two blocks are supported by a pulley along an incline as shown. The lower block B has a weight of 28 lbs and the higher block A has a weight of 15 lbs. Assume that there is friction between the blocks with H3 = 0.13 and assume friction between block B and the incline is also 4, = 0.13. Determine the angle r for which motion is impending. 151b 2816 A Tension in block A as a function of z can be written as TA %3| Tension in block B as a function of z can be written as TR Thus, impending motion is at z = degrees.
