Chapter $16$ Problems:

In the following problems, the given loads are superimposed service loads; that is$,$ they do not include the weights of the beams $($unless noted otherwise$).$ For structural steel beams $($unless otherwise noted$),$ assume a yield stress of $).$ For timber beams, all beams are solid, rectangular shapes and Appendices and $F$ are applicable. Consider only moment and shear $($unless otherwise noted$).$

$16\mathrm{.}2$ A simply supported beam is to support a uniformly distributed load of $10$ kips$/ft.$ Select the lightest $W$ shape. The span length is $32ft.$ Deflection is not to exceed span$/240.$ Neglect beam weight.

$16\mathrm{.}6$ A simply supported beam is to span $15ft.$ It will support a uniformly distributed load of $2$kip$\frac{s}{f}t$ over the full span and a concentrated load of $60$kips at midspan. Deflection is not to exceed span$/240.$ Select the lightest $W$ shape.
