Introduction
In recent years, innovative means of enhancing
structural functionality and safety against natural and
man-made hazards have been in various stages o
Method of Section
Method of sections is a powerful tool to determine forces in statically determinate plane
structures. A section is cut through the truss such that it cuts at the maximum three
members in which forces are unknown.
Why Method of Sections?
Q.1 What is SHM (simple harmonic motion)? Describe it in terms of
displacement, amplitude, restoring forces, equilibrium, and acceleration. What
is the period and frequency? How does the energy change throughout a
complete cycle? (3%)
Ans:
Simple harmonic
Isometric Drawing
Isometric drawing is way of presenting designs/drawings in three dimensions. In order for a
design to appear three dimensional, a 30 degree angle is applied to its sides.
It is a method for visually representing three-dimensional objects
Trusses
Introduction: A truss is a structure composed of slender members joined together at end
points by bolting/riveting or welding. Ends of the members are joined to a common place
called gusset plate.
Assumptions for design of truss members and connec

Bending Moment Diagram
Definition of Bending Moment: Bending moment at a section is the resultant moment at a
section due to all the transverse forces either to the left or right of the section.
At sections, where the bending moment is such that it tends
Shear Force Diagram
Definition of Shear Force: Shear force at a section is the resultant of all transverse forces
to the right or left of the section.
SF at a section is +ve if resultant of all transverse forces to the right of the section is
downward or
Concept for solving Pipeline Network
To analyse the pipe network, Hardy Cross Method is used.
Hardy Cross Method:
The general relationship between head loss and flow is:
where k is the head loss per unit flow and n is the flow exponent. In most design sit
