In a cantilever carrying a uniformly varying load starting from zero at the free end, the Bending moment diagram is
A)A horizontal line parallel to x-axis
B)A line inclined to x-axis
C)Follows a parabolic law
D)Follows a cubic law

Question

Quizplus · Accepted Answer

The bending moment in a cantilever with a uniformly varying load from zero at the free end follows a cubic law because the load intensity varies linearly, leading to a quadratic shear force and a cubic bending moment distribution.
