Question

The maximum bending moment of
a simply supported beam having a
span L and subjected to a uniformly
varying load W having a zero
intensity at one support and
maximum at the other is *
O WL^2/8
O WL^3 / 903
WL^3/8
O WL/973​

Answer 1

Answer:

Support reactions are Vay = wl/2 = Vby.

Cut s/n and take the moment at pont zero.

M = - (wx^2/2) +wlx/2.

Max moment at mid pnt l/2.

M = Wl^2/8.

For uniformly distributed load moment varies parabolically not linearly.
