Adiver weighing 200 pounds jumps from 1 foot above a diving board made from a 1-inch by 16-inch, 5-foot-long aluminum beam. e = 10.4 x 10? psi calculate: • maximum deflection • maximum force in the board. • maximum stress.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
