THE AREA-MOMENT / MOMENT-AREA METHODS:
The area moment method is a semi graphical method of dealing with problems of deflection of
beams subjected to bending. The method is based on a geometrical interpretation of definite
integrals. This is ap

Deflection of Beams
Introduction:
In all practical engineering applications, when we use the different components, normally we
have to operate them within the certain limits i.e. the constraints are placed on the performance
and behavior

Pumps
Rotodynamic Pumps
A rotodynamic pump is a device where mechanical energy is transferred from the rotor to the fluid by the principle of fluid motion through it. The energy of the fluid can be
sensed from the pressur and velocity of the fluid at the

Simple Bending Theory OR Theory of Flexure for Initially Straight Beams
(The normal stress due to bending are called flexure stresses)
Preamble:
When a beam having an arbitrary cross section is subjected to a transverse loads the beam wi

Procedure for drawing shear force and bending moment diagram:
Preamble:
The advantage of plotting a variation of shear force F and bending moment M in a beam as a
function of x' measured from one end of the beam is that it becomes easier
LECTURE 28 and 29
Shearing stress distribution in typical cross-sections:
Let us consider few examples to determaine the sheer stress distribution in a given X- sections
Rectangular x-section:
Consider a rectangular x-section of dimension b and d
A is the

Analysis of Stresses:
Consider a point q' in some sort of structural member like as shown in figure below. Assuming
that at point exist. q' a plane state of stress exist. i.e. the state of state stress is to describe by a

ANALYSIS OF STERSSES
General State of stress at a point :
Stress at a point in a material body has been defined as a force per unit area. But this definition is
some what ambiguous since it depends upon what area we consider at that point. Let u
