A 20 kip load is applied at point B to a rigid bar that is connected to a A-36 steel cables at point A and C. The steel cables attach to supports at D and E. The steel cables have a cross-sectional area = 0.3 in2. Determine the vertical displacement of points A, B, and C.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
