HW$09\mathrm{.}2-$ The beam is supportec by a pin at A and by springs at $B$ and $C.$ The beam is horizontal when the $600-N$ force is not applied. Find the angle of tilt of $t$ beam after the $600-N$ force is applied.

Process:

Draw the free$-$body diagram of the beam including the $600-N$ applied load.

Derive an equilibrium equation for the summation of moments about $A.$

Consider that when the $600-N$ force is applied, the beam will rotate slightly about point $A.$ Derive a relationship between the change in length of spring $B$ and the change in length of spring $C.$ This relationship will be a result of the geometry, not equilibrium equations

Using the equations you derived in $2.$ and $3.$ find the force in both springs.

Use the equation for the force in a spring to find the change in length of the springs

From the change in length of the springs, find the angle of tilt of the beam.
