Q26 A 6 m long simply supported wooden beam carries a 36 kN concentrated load at B. The cross-sectional dimensions of the beam are b = 100 mm, d = 300 mm, a= 85 mm, and c = 25 mm. Section a-a is located at x = 0.8 m from B. Determine (a) The magnitude of the shear stress in the beam at point H in section a-a. (b) The magnitude of the shear stress in the beam at point K in section a-a. (c) The maximum horizontal shear stress that occurs in the beam at any location within its entire span. (d) The maximum tensile bending stress that occurs in the beam at any location within its entire length.

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.
