STATICALLY DETERMINATE STRUCTURE:

Statically determinate beam:

Using the equations of equilibrium given below, if all the reaction components can be found out, then the beam is a statically determinate beam.

The equations of equilibrium are

ΣFx= 0 ΣFy= 0 ΣM= 0

Analysis of plane truss:

A plane truss is when the members of the truss lie in a single plane (2D analysis).

Simple truss

The basic element of a plane truss is a triangle. Three bars joined by pins at their ends constitute a rigid frame.

A non-rigid, moveable frame can be made with four or more bars joined at their ends. This can be made rigid by addition of a diagonal bar.
