Calculate the load trace for a sloped roof structure.
\left. \begin{matrix} Roofing = 5 psf \\ Roof \space Sheathing = 3 psf \\ Rafters = 4 \#/ft. \end{matrix} \right\} Along \space rafterSnow load (SL): 40 psf on horizontal projection of rafter*
Beam: 16 \#/ft.
*Snow loads are normally given as a load on the horizontal projection of a roof.
