Expert Solution

Step 1

Explanation:

The fixed and roller supports are mainly used in the truss application for supporting the ends. The roller support or rocker supports are used in truss bridges.

The only one reaction is created at the roller support and two reactions are created at the fixed support.

The Fixed support of the truss does not allow any deformation due to change in temperature or due to application of load.

So, The roller support is mainly provided at one end of trusses to allows freedom for contraction or expansion of the members due to change in temperature or the application of loads.
