Rod bd is made of steel 6 ( 29 10 psi) e   and is used to brace the axially compressed member abc. the maximum force that can be developed in member bd is 0.02p. if the stress must not exceed 18 ksi and the maximum change in length of bd must not exceed 0.001 times the length of abc, determine the smallest-diameter rod that can be used for member bd

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.
