Given: Rigid bar ABC and three wires suspended between the ceiling and $A,B,C.$ Same $E$ and A for

each wire. $P$ is given.

Solve$/$Answer:

Force equilibrium equation$($s$),$ and free$-$body diagram or $N$ diagram specific to this problem $(15$

points$).$

Compatibility equation$($s$)$ and deformation formula$($s$)$ specific to this problem $(15$ points$).$

Material property$/$properties specific to this problem $(2$ points$).$

Cross$-$sectional property$/$properties specific to this problem $(2$ points$).$

The rest of the calculations to determine the tension in each wire $(10$ points$).$

Is this a statically determinate problem $(2$ points$)?$ Why or why not $(4$ points$).$
