Part A

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

$w_1=1\mathrm{.}7k\frac{N}{m}$ and $w_2=2\mathrm{.}2k\frac{N}{m}.$ The angle

between the cable and the beam is $=40.$

Determine the normal force, shear force, and

bending moment acting at point $B,$ located $x=0\mathrm{.}9$

$m$ to the left of the end of the beam.
