Problem $2(30$ points$)$

Three pieces of wood each $\frac{33}{4}$ inches wide are glued together as shown below.

a$.$ If the joint carries a load of $P=4,500$ pounds, what is the average shearing stress developed in

the glued joint?

b$.$ If the maximum allowable shear stress of the glue is $550$ psi, what is your calculated factor of

safety?

c$.$ If we want to maintain a factor of safety of at least $3,$ what could you change in the design to

meet this requirement? Please describe what you would do and then calculate the change to

show if your proposed plan works $($please show the calculation$).$

d$)$ If we replace the glue joint with a $\frac{3}{8}$ bolt

Passing through all $3-$menbers, what oheen

stress mull the boit see?
