Step 1
The vertical component of the force in BC must balance the applied load P. Therefore, the force in member BC ($F_{BC}$) is given by: $F_{BC} = \frac{P}{\sin(\theta)}$ Show more…

If a horizontal load applied to the bar $A C$ causes point $A$ to be displaced to the right by an amount $\Delta L,$ determine the normal strain in the wire $A B .$ Originally, $\theta=45^{\circ}$.

The wire $A B$ is unstretched when $\theta=45^{\circ} .$ If a load is applied to the bar $A C,$ which causes $\theta$ to become $47^{\circ}$ determine the normal strain in the wire.
