    Engineering Diagram of a beam with distributed load - SOLVED

    Hi guys, I'm wasting much time on this problem but still can't manage to get to a solution; I'll attach my attempt below. I started with drawing the FBD of the beam "sectioned" at point C, in order to find an expression for the internal shear force at that point and then equal that to zero...

    Choosing correct steel beam for a span

    I have a weight of 30,000 lbs distributed across a span of 100' and supported at the ends. If I have 3 beams to support this load, each beam would then need to hold 10,000 lbs, and with a F.S of 1.6 each beam would need to hold 16,000 lbs. If I assume my max deflection at 1", then I can find the...
