UPSC Civil Service Exam Questions - Engineering

Q1:

Consider the following statements :
In the beam shown in the given figure, for all positions of load W (except x = 0)
1. bending moment is maximum at B
2. bending moment is maximum under load
3. deflection is zero at A
4. deflection is zero at B
Of these statements :

A 1 and 3 are correct

B 2 and 4 are correct

C 1 and 4 are correct

D 1, 3 and 4 are correct

ANS:D - 1, 3 and 4 are correct

Option "C" could not be considered as correct because this is not a cantilever.

As there is a vertical reaction at support "A", so option "D" is correct.
