Question

Where do you find trusses in use? What are the various methods of analysis of trusses? What is basically found when analysis of a system is done?

Answer 1

The main use of truss are:

1. The trusses are used to support slopping roofs.

2. Brick trusses are used in bridges to support deck etc. Analysis of a frame consists of,

(a) Determinations of the reactions at the supports.

(b) Determination of the forces in the members of the frame. The forces in the members of the frame are determined by the condition that every should be in equilibrium. And so, the force acting at every should form a system in equilibrium. A frame is analyzed by the following methods,

1. Method of *****.

2. Method of section.

3. Graphical method.

When analysis is done, we are basically calculation the forces acting at each ***** by which we can predict the nature of force acting at the link after solving our basic equation of equilibrium.
