BENDING STRESSES IN BEAMS
Bending is usually combined with the shearing
action. However, to simplify, the effect of shear
may be neglected ( this is true when the maximum
bending moment is considered- shear is ZERO)
in calculating the stresses due to

SHEAR STRESSES IN BEAMS
Introduction:
In the earlier chapter, the variation of bending stress across
a beam section was studied. The bending stress is due to
bending moment at the section. A typical beam section is
subjected to shear force in addition t

INTRODUCTION
The state of stress on any plane in a strained body is said to be
Compound Stress, if, both Normal and Shear stresses are acting
on that plane. For, example, the state of stress on any vertical
plane of a beam subjected to transverse loads wi

INTRODUCTION
The cross section of a beam has to be designed in such a
way that it is strong enough to limit the bending moment and shear
force that are developed in the beam.This criterion is known as the
STRENGTH CRITERION of design .Another criterion
