For the truss below, determine the horizontal displacement at Node $C$ using principle of Virtual Work. Each member has a cross$-$sectional area $\text{'}A\text{'}=300m{m}^2,E=200$GPa,&$P=10kN.$ The applied loads are provided in terms of $P.$ The resulting member forces due to applied loads $(N_i)$ are provided in parentheses.

HINT: Simplify using Zero force members.

a$)$ Clearly indicate using a new schematic of the truss, the location of virtual load, its direction, value, and resulting reactions and member forces of the entire truss.

Points

b$)$ Application of principal of virtual work...

c$)$ Final value of displacement and its direction....
