Learning Goal:

To calculate the internal normal force, shear force, and bending moment at a point in a beam.

A beam with length $L=2\mathrm{.}2m$ is supported by a pin joint at A and a cable attached at $C$ as shown in $($Figure $1).$ It is subjected to the distributed load with $w_1=1\mathrm{.}4k\frac{N}{m}$ and $w_2=1\mathrm{.}9k\frac{N}{m}.$ The angle between the cable and the beam is $=40.$ Determine the normal force, shear force, and bending moment acting at point $B,$ located $x=0\mathrm{.}6m$ to the left of the end of the beam.

Part A

Begin by finding the support reactions for the beam using the free$-$body diagram shown in $($Figure $2).$ What is the tension in the cable?
