Problem $7\mathrm{.}21$

$4$ of $6$

Consider the compound beam shown in $.$ Suppose that $P_1=830N,$

$P_2=1150N,$

$w=450\frac{N}{m},$

and point $E$ is located just to the left of $830N$ force. Follow the sign convention.

Part A

Determine the internal normal force at point $E.$

Express your answer to three significant figures and include the appropriate units.

I need NE$,$ VE$,$ ME

PART B

I need NF$,$ VF$,$ MF
