Consider the overhang beam shown in $($Eigure $1).$ Suppose that $P=6kN,M=7kN*m,w=4k\frac{N}{m}.$ Point $D$ is located just to the left of the roller support at $B,$ where the couple moment acts. Follow the sign convention.

Determine the internal normal force at point $D.$

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