A $48$ Spruce$-$Pine$-$Fir $($No$.2)$ is connected to a single $26$ using two lag screws as shown.

The connection was fabricated in dry conditions and is used in wet conditions with

temperatures less than $90F.$ Use $\frac{5}{8^{\text{'}\text{'}}}$ dia. $-5$ in$.$ long standard hex lag screws. D$+$L

governs.

a$.$ Determine the predrilled hole size required for the lag screw installation.

b$.$ Evaluate whether the connection meets spacing and end$/$edge distance requirements

for these lag screws.

c$.$ Determine the total connection capacity, $Z^{\text{'}}.$

d$.$ Compare your result with HW$9-$problem $1.$

Discuss differences that would affect your

comparison.
