1.	A simple truss ABC is supported at A and B as shown in the figure. If a point load (P) along BC is applied at joint C in horizontal direction, then what will be the vertical deflection at C? Assume same C/5 area and same materials (i.e., A, E, I same for all members).
A.	\(\frac{PL}{AE}\)(↑)
B.	\(\frac{2PL}{AE}\)(↓)
C.	\(\frac{PL}{AE}\)(↓)
D.	\(\frac{2PL}{3AE}\)(↓)
Answer» D. \(\frac{2PL}{3AE}\)(↓)
