QUESTION: 1

If shear force diagram between two sections is constant, BM diagram between those two section varies

Solution:

QUESTION: 2

A simply supported beam of length ‘l’ is subjected to a point load at mid-span. The shape of BMD is

Solution:

QUESTION: 3

Between point loads the shear varies

Solution:
Shear force is constant between two point loads.

QUESTION: 4

The shear force diagram for a cantilever subjected to uniformly distributed load over its entire span is

Solution:

SF_{X−X} = wx

QUESTION: 5

A beam is said to be in general stable and statically determinate for general loading when number of reaction components is

Solution:

QUESTION: 6

The reaction at a hinged support of a beam is

Solution:

QUESTION: 7

For overhanging beams, the point of contra flexure

Solution:

→ Point of contraflexure is a point where bending moment changes its sign.

→ As from the BMD it is clear that in between the supports the BM is changing the sign.

QUESTION: 8

At a point of contra flexure

Solution:
It is the point where the BM is zero after changing its sign from positive to negative or vice versa.

QUESTION: 9

Maximum bending moment occurs in simply supported beam, where the [

Solution:

QUESTION: 10

In a beam under loading

Solution:

QUESTION: 11

For a beam subjected to a constant bending moment throughout its length

Solution:

QUESTION: 12

The difference in ordinate of the shear curve between any two sections is equal to the area under

Solution:

QUESTION: 13

A lever is supported on two hinges at A and C. It carries a force of 3 kN as shown in the above figure. The bending moment at B will be

Solution:

QUESTION: 14

The shear force at the free end of an overhanging beam (with udl) is equal to

Solution:

Shear force will increase linearly from end D to support B starting from zero.

QUESTION: 15

A wooden log of length 5mm is floating in water. First it’s self-weight is 1kN/m. The maximum B.M at the center is

Solution:
Due to self-weight SF and BM will not occur when the member is freely floating.

QUESTION: 16

Bending moment in a simply supported beam is maximum at

Solution:

QUESTION: 17

Bending moment in a cantilever beam shown below will be zero at

Solution:

QUESTION: 18

When a SSB is subjected to a concentrated moment at a distance of L/4 from the right end, the maximum bending moment occurs at

Solution:

QUESTION: 19

Shear force at any section is the algebraic sum of the following force on the either side

Solution:
Shear force at any point or at any section is the algebraic sum of transverse shear forces either to the left or to the right of a section.

QUESTION: 20

For a simply supported beam of length ‘l’ subjected to downward load of uniform intensity w,
