## Theory of Structures Pick up the correct statement from the following:

All of these
In a loaded beam, the moment at which the first yield occurs is called yield moment
In a fully plastic stage of the beam, the neutral axis divides the section in two sections of equal area
In a loaded beam, the moment at which the entire section of the beam becomes fully plastic, is called plastic moment

## Theory of Structures A compound bar consists of two bars of equal length. Steel bar cross -section is 3500 mm²and that of brass bar is 3000 mm². These are subjected to a compressive load 100,000 N. If Eb = 0.2 MN/mm² and Eb = 0.1 MN/mm², the stresses developed are:

b = 6 N/mm² s = 12 N/mm²
b = 5 N/mm² s = 10 N/mm²
b = 8 N/mm² s = 16 N/mm²
b = 10 N/mm² s = 20 N/mm 2

## Theory of Structures The assumption in the theory of bending of beams is:

Material is isotropic
Material is homogeneous
Young’s modulus is same in tension as well as in compression
All of these

4p/a²
3p/a²
p/a²
2p/a²

All of these
V = 0
H = 0
M = 0

Hooke’s ratio
