Air enters the compressor of an ideal gas refrigeration cycle at 17°C and 35 kPa and the turbine at 47°C and 160 kPa. The mass flow rate of air through the cycle is 0.3 kg/s. Assume variable specific heats for air, a compressor isentropic efficiency of 80 percent, and a turbine isentropic efficiency of 85 percent. (Take the required values from the ideal-gas properties of air tables.) Determine the net power input. (You must provide an answer before moving on to the next part.) The net power input is 1.7 kW.

What is the reaction of shear stress on the cross-section?
Learning Goal: To analyze two built-up members that have the same geometry but are fastened differently, determine the maximum applicable shear force on each cross section, and determine the adjustment in spacing between the weaker member's fasteners that would allow the member to support the equivalent maximum shear force of the stronger member. The two cross sections shown below, (a) and (b), are subjected to a vertical shear force as shown. The members are fastened by nails that can support a load of 22.00 kN each and are spaced perpendicularly to the page in increments of s = 125.0 mm. The geometries of the cross sections are given by a = 235.0 mm, b = 50.00 mm, c = 225.0 mm, d = 135 mm, and e = 275 mm. Assume the cross sections are uniform along the entire lengths of the members. bk (a) Part A - Maximum applicable shear force on the member (a) *ak b 17 b ➜bk ➜bk Determine the maximum applicable shear force on the member (a).
