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.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
