Determine the minimum width of a 30ft long cantilever W14 steel I-beam that carries a uniform 300 lb/ft load without exceeding a maximum allowable bending stress of 30 ksi. Then, check that the allowable shear strength of 15 ksi is not exceeded. Finally calculate the deflection of the beam at B for the chosen width

Answer rating: 100% (QA)

To determine the minimum width of the W14 steel Ibeam we can use the formula for the maximum bending stress sigmamax in a beam sigmamax MmaxS where Mm... View the full answer
