WL^2/8.
Z = I/Y.
Z called section modulus.
F = M/Z.
Z =(BD^2/6)=540.
M = WL^2/8,
(WL^2/8)/(10*18^2/6).
W = 540 * 8/4^2,
W = 270KG,
W = 540 * 8.

Thanks for the answer.

Why you takes length in meters? All dimension take into cm than the answer is different.

W=270 is right.

D. 270 is the answer I think.

Every time, assume SSB if there is not any information about support.

In question there is no information about beam type.
Ranjit said:

But the type of beam is not given here then how can we use simply supported condition?

F= My/I.
M = (WL^2) /8.
M = fI/y = wl^2/8.
I = bh^3/12.
Y = h/2.
F and l are known, then we get,
W= 270 kg.
M = (WL^2) /8.
M = fI/y = wl^2/8.
I = bh^3/12.
Y = h/2.
F and l are known, then we get,
W= 270 kg.
