It's Wa^2b^2Ã·3EIl.

Option A is for point load at the centre.

Simply supported beam Wl^3/48EI.
Simply supported with UDL -5WL^4/384EI.
Both ends fixed -WL^3/192EI.
Both ends fixed with UDL -WL^4/384EI.

Since the load is applied Centrally.

a=b=L/2.
we have y=(w.a^2.b^2)/3EI.L putting above values in this we get,
y=(wL^3)/48EI.

I think 5wl^4/384EI is the correct answer.

RAJIV RANJAN said:   7 years ago
For the given condition y=w(a^2 *b^2)/3EIL.

A is correct. Read the question carefully. Weight W is act in centre.

Option A is right. I agree.
