Switch To Light Mode calculation steps, and enclose your answer, including units, in a rectangular box. Use additional lined paper for descriptions and engineering paper for calculations.

For ALL Problems: Hand drafting is required for this homework. Use a straight$-$edge. The drawings are part of the graded work. Use load combinations $($PSD pg$.15).$

Calculate Combination Load using equations $1\mathrm{.}21$ through $1\mathrm{.}25$ as required for the loads given. Do NOT calculate Live Load Reduction for any problem.

Problem $1-$ A framing system consists of the following: sheathing $(4$ psf $),$ floor or roof covering $(3$ psf $),2$ in$.12$ in$.$ framing at $24$ in$.$ on center $(2\mathrm{.}6$ psf $),$ ceiling supports $(0\mathrm{.}5$ psf $),$ and gypsum wallboard ceiling $(5$ psf $).$ The framing members are $12\text{'}$ long. Determine the floor dead load and draw the loaded framing member.

Problem $2-$ A roof framing section is shown below. The length of the building is $40$ ft $.$ The ridge beam has supports at two ends and at midlength. Using the dead load in Problem $1,$ determine the roof live load and dead load on the ridge beam. If joists are spanning between the ridge beam and the wall and are spaced at $32$ o$.$c$.,$ determine the roof live load and dead load on the joist and the reactions on either end. Draw the associated roof plan.
