Consider the truss shown in $($Figure $1).$ Assume the members are pin connected at their end points. Take $A=4i{n}^2$ and $E=29({10}^3)ksi$ for each member

Correct

Here we learn how to determine the correct equation of the method of virtual work for the displacement in trusses

Revien

Part B

Determine the vertical displacement of joint A measured downward. Use the method of virtual work.

Express your answer using three significant figures. Enter positive value if the displacement is downward and negative value if the displacement is upward.
