Adiving board is to be designed that is 6 foot long, 14in wide. the maximum load at the end of the beam is 400lb. the diving board can be considered a cantilever beanm 2. a. draw a free body diagram of the beam b. draw the shear force diagram and bending moment diagram for the beam c. assuming the material is made of wood and the maximum normal stress ( must not exceed 4kps, determine the required height of the beam for a rectangular section.

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?
