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 Ha = 0.13 and assume friction between block Band the incline is also 4, = 0.13. Determine the angler for which motion is impending.

![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.

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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa4e23d50-b6e1-4880-9ad9-a789799b751b%2F89dcacea-9960-4046-a6eb-3bc3398258f1%2Ffh86dz3_processed.png&w=3840&q=75)
