Problem $3(30$ pts$.)$

A roof system with W$21$x$44$ sections spaced $7ft$ o$.$c$.$ is to be used to support a dead load of $42$

psf$,$ a roof live load, snow or rain load $(L_r$ or $S$ or $R)$ of $28$ psf$,$ and a wind load of $+12$ and $-16$

psf$.$ Assume the snow load to be $28$ psf$.$ Determine the governing factored load. Use the LRFD

method.
