Given the following:

Compute reactions here

a$)$ Solve for the reactions then neatly draw the shear and bending moment diagram, showing the

max$/$min values. Use $2$ decimal places for consistency.

M

c$)$ If the beam is made up of a $4^{\text{'}\text{'}}{8}^{\text{'}\text{'}}$ Douglas Fir member $($Actual size: ${3\mathrm{.}5}^{\text{'}\text{'}}{7\mathrm{.}25}^{\text{'}\text{'}},I=111\mathrm{.}1i{n}^4),$

compute the maximum bending stress $(f)$ developed in the beam.

d$)$ For the same beam mentioned in part c $,$ compute the maximum shear stress $(f_v)$ in the beam.
