A simply Supported Steel "I Beam" is made of three 1" x 7" plates with a mass of 898.4 lbm each as shown below. Steel has a modulus of elasticity of 30x10^6 psi. The beam is allowed to deflect 1.10 in. The length of the beam L between supports is 10.5 feet.

a) If i turn the same beam clowise 90 degrees, what percentage of the problem 20 maximum load can i apply to yield the same 1.10 inch deflection? (report result to 1 decimal place).

A 356 x 171 US45 steel beam is simply supported at the ends of a span of 5.5 m. The beam carries a safe inclusive UDL of 12kN/m and a point load of 75 kN at mid-span. Calculate the maximum deflection due to this load. Let: E = 205 000 N/mm2 I = 12070 cm4 deflection δPL = PL/48EI deflection δudL = 5wL3/384EI

For a simply supported beam of length L and uniform cross-section (constant E and I with usual notation) with a concentrated load P perpendicular to the beam at mid span, use first principles and method of integration discussed to obtain an expression for the maximum deflection. If the concentrated load is still perpendicular to the beam but not at the mid span, very clearly and briefly explain how you would determine the maximum deflection of the beam.
