The following cantilever beam is loaded with a distributed load of w = 2kip/ft. The length is L = 15ft, and the Young’s Modulus is 29,000ksi. The height of the beam is to be two times the base width (so h = 2b). If the maximum deflection is L/360 and the maximum stress is 30ksi, what should the dimensions be? Show that you’ve checked for both stress and deflection in your answer. (20 points)

2.     The dimensions of the beam below are to be h = 3b. The beam is 7 feet long with a distributed load of 15kips/ft. It is made of steel with E = 29,000ksi. The maximum stress can be 40ksi and the maximum deflection is L/180. What should h and b be to meet strength and deflection requirements? (20 points)

3.     The following wooden beam (E = 1900ksi) is loaded in the center with a point load P = 15kips. The maximum allowed deflection is L/240 and the maximum allowable stress is 10ksi. If the dimensions are b = 6 inches and h = 8 inches, what is the greatest possible length? (20 points)

4.     The following cantilever beam is loaded with a point load P. The maximum deflection is L/180 and the maximum strength is 30ksi. It is made of steel with E = 29,000ksi. If the length of the beam is L = 20ft and the dimensions of the beam are b = 8 inches and h = 14 inches, what is the maximum load that can be placed on the beam (considering both strength and deflection – find which is the limiting factor)? (15 points)
