A rigid bar is supported by a spring as shown in the given figure.

The deflection of the point B will be

[A]. 10 mm upward
[B]. 20 mm downward
[C]. 5 mm upward
[D]. 40 mm downward.

Answer: Option D


The Force in spring F = (500x2L)/L = 1000N.

Deflection in the spring δ = F/k = 1000/50 = 20mm.

Deflection at the point B = 2δ = 40mm downward.
