Structural Metals Supply, Inc. has recently been contracted to design a beam for an overhead crane system. I would like you to conduct tests and provide verification of the beam deflection equations published in many textbooks and then use these equations to design a simply-supported steel or aluminum beam with a rectangular cross section to span 30 feet. The beam will support two equal crane loads of 10,000 pounds at 10 and 20 feet. The maximum beam deflection should be less than L/360. Please provide the least expensive solution using current commodity prices for steel ($1.03/lb) and aluminum ($1.12/lb). To ensure stability of the beam, the maximum height to width ratio of the cross section should be h/b = 2.0. Please use a factor of safety of 1.5 against yielding and use published values for yield strength and modulus of elasticity. Please provide the width (b) and height (h) of your recommended beam to the nearest half inch. Also, consider the self-weight of the beam in your design.

A 5-kip crate is supported by a pulley system and a horizontal force P.a) Find P and the angle α. Report your answer in kips (1 kip = 1000 lbs).b) For this problem if you double the weight of the crate, will the force P double? Briefly explain why or why not.
What is the value of the long term deflection for the double reinforced beam having a base of 250 mm, d of 400 mm, As = 3000 mm^2, As' = 1000 mm^2. If the computed value of deflection deadload = 5.50 mm, deflection live load = 10.00 mm, deflection sustained live load = 7.00 mm. The long term deflection to be considered is 8 years.
Provide the details in your solution. The maximum safe load of a horizontal rectangular beam of a given material,supported at the ends, varies directly as the breadth and the square of the depth, and inversely as the distance between supports. If the maximum safe load is 3000 lbs for a beam 5 inches wide and 12 inches deep, with supports 12 feet apart, find the maximum load for a beam which is 10 cm wide and 10 inches deep, with supports 3 meters apart.
