Consider the frame shown in $.$ Suppose that $w_1=4\mathrm{.}5\frac{k}{f}t$

and $w_2=3\frac{k}{f}t.$

Part A

Determine $($approximately$)$ the moment at joint $D$ from $DE.$

Express your answer in kilopound$-$feet to three significant figures. Enter a positive value for a counterclockwise

moment and a negative value for a clockwise moment.

$M_D=|,k*ft$

Part B

Determine $($approximately$)$ the moment at a fixed support $B.$

Express your answer in kilopound$-$feet to three significant figures. Enter a positive value for a counterclockwise

moment and a negative value for a clockwise moment.

$M_B=,k*ft$
