Q1:

A cantilever of constant depth carries a uniformly distributed load on the whole span. To make the maximum stress at all sections the same, the breadth of the section at a distance x from the free end should be proportional to

A x

B
x

C x2

D x3

ANS:C - x2

@All.

Remember the relation;

#for the cantilever:-
b is proportional to x^2,
And d is proportional to x.

#for SSB:-

b is proportional to x.
d is proportional to x^1/2.
