Solution:

(Bending formula)

QUESTION: 2

Solution:

QUESTION: 3

### The product El is known as

Solution:
QUESTION: 4

The assumption “the plane section before bending remains plane after bending” made in the theory of bending implies:

Solution:
QUESTION: 5

At the neutral axis of simply beam, there is

Solution:

Bending stress,

where y is the distance of any fibre from the neutral axis.
For the neutral axis, y = 0, ∴ σ = 0

QUESTION: 6

For a beam of uniform strength, if its depth is kept constant, then its width will vary in proportion to

Solution:

for beam of uniform strength, σ = constant at any section
so, M α Z

∴ M α width

QUESTION: 7

When a rectangular beam is loaded longitudinal, shear develops on

Solution:
QUESTION: 8

A beam is said to be of uniform strength, if

Solution:
QUESTION: 9

A rod of length L and diameter D is subjected to a tensile load P. Which of the following is sufficient to calculate the resulting change in diameter?

Solution:
QUESTION: 10

Beams of uniform strength so vary in section that the

Solution:

Unit stress means stress at any section.
