Expert Solution

Step 1

The given beam is shown below –

Calculating reaction at support at A and B,

Step 2

Calculation for Shear Force Diagram,

The shear stress will be 0 at section CB obtained by putting the above equation to 0.

Step 3

Now drawing the SFD as shown below –

Calculating the bending moment at the different section as follows –

For section, CB consider at a distance x from C

For maximum bending moment differentiate the above equation with respect to x and put it to 0.
