During your investigation and research into simple truss$/$framework design you are. required to comprehensively report on the following:

Understand and explain what is meant by the term 'two$-$dimensional framework.

Understand and explain the stability concepts of a framework.

Understand the nature of the forces and stresses induced in the members of a twodimensional framework due to externally applied loads.

Be familiar with the various methods of calculating internal forces in the members of simple trusses.

Derive expressions for the state of frameworks with or without foundations.

Using the knowledge gained from your research into two$-$dimensional frameworks and modules such as stress and strain. you must be able to correctly and accurately calculate the required design values as alipulated by the client's specifications.

Present all the above, i$.$e$.$ your designs, calculations and findings in a comprehensive technical report as per Professional Communication Studies $($PFC$150$S $/$ PFC$150$X$).$

Detaile for the hridore truce decion.

A Warren girder bridge truss that will be subjected to loads as shown above is to be designed and analysed for the client. All triangles are to be equilateral triangles and member a$-$b is $2$ m long. As per the design requirements the following needs to be calculated:

State the nature of the framework.

Calculate the reactions at the supports.

$4$

Using the method of sections $($analytical method$),$ calculate the magnitude of the internal forces in member b$-$c$,$ b$-$g and g$-$h and state the sense $($nature$)$ of each force.
