Question

What would be the reactions if the beam is statically indeterminate?

Expert Solution

Step 1

If the number of actual reactions in a member is greater than the number of useful static equilibrium equations then it is termed as statically indeterminate system.

The three static equilibrium equations are :

They represent summation of all the forces in horizontal ,vertical directions is zero and net moment about any point in the system is zero respectively.

Step 2

Let us consider an example of continuous beam having point loads.

The beam has two hinge supports at A and B and a roller support at C.W is the external point loads on the beam.
