Question

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, w…

Accepted Answer

Option D. 8/5. Answer & Solution Answer: Option D Solution: & Deflection max ( A ) = P L^348 EI & Deflection max ( B ) = 5 w L^4384 EI;\,\,\, ( w = P L ) & = 5 P L^3384 EI & Ratio = P L^348 EI × 384 EI5 P L^3 = 8/5

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
