Question:-
A cantilever of length L, moment of inertia I, Young’s modulus E carries a concentrated load W at the middle of its length. The slope of cantilever at the free end is
Option (A)
WL2/2EI
Option (B)
WL2/4EI
Option(C)
WL2/8EI
Option(D)
WL2/16EI
Correct Option:
(C)
Question Solution:
Slope (when load acts free end) = WL2 / 2El
Slope (when load acts mid-span) = {W(L/2)2 / 2El} = (WL2 / 8El)
