### 1.

## A simply supported beam A carries a point load at its mid span. Another identical beam B carries the same load but uniformly distributed over the entire span. The ratio of the maximum deflections of the beams A and B, will be

## Answer & Solution

Answer:

**Option D**Solution:

Def.max (A)= PL3/48EI;

Def.max (B)= 5wL4/384EI; w=P/L,

= 5PL3/384EI.

Ratio= (PL3)/48EI * 384EI/(5PL3) = 8/5.
