Expert Solution
Step 1
The component always breaks at point C, which is just right of the contact point of the roller at B. So, draw the free-body diagram of the section which is just right of the contact point of the roller at B as follows:
Here, the reaction force at C in the horizontal direction is RCx, the reaction force at C in the vertical direction is RCy and the moment reaction at C is MC.
Step 2
Consider the equilibrium of force in the horizontal direction,
Consider the equilibrium of force in the vertical direction,
Calculate the moment reaction at C,
Step 3
Therefore, the internal forces in terms of shear, normal, and bending are,
