Chapter 7.3, Problem 7.40P

The simply supported beam is built up from three boards by nailing them together as shown. The wood has an allowable shear stress of τ_allow = 1.5 MPa, and an allowable bending stress of σ_allow = 9 MPa. The nails are spaced at s = 75 mm, and each has a shear strength of 1.5 kN. Determine the maximum allowable force P that can be applied to the beam.

Q2: (15 Marks) A water-LiBr vapor absorption system incorporates a heat exchanger as shown in the figure. The temperatures of the evaporator, the absorber, the condenser, and the generator are 10°C, 25°C, 40°C, and 100°C respectively. The strong liquid leaving the pump is heated to 50°C in the heat exchanger. The refrigerant flow rate through the condenser is 0.12 kg/s. Calculate (i) the heat rejected in the absorber, and (ii) the COP of the cycle.

A mass of ideal gas in a closed piston-cylinder system expands from 427 °C and 16 bar following the process law, pv1.36 = Constant (p times v to the power of 1.36 equals to a constant). For the gas, initial : final pressure ratio is 4:1 and the initial gas volume is 0.14 m³. The specific heat of the gas at constant pressure, Cp = 0.987 kJ/kg-K and the specific gas constant, R = 0.267 kJ/kg.K. Determine the change in total internal energy in the gas during the expansion. Enter your numerical answer in the answer box below in KILO JOULES (not in Joules) but do not enter the units. (There is no expected number of decimal points or significant figures).
