Example 5.16 Find the expression for the prop reaction in the propped cantilever beam shown in the Figure 5.19(a).
 

 

Solution: Let reaction at support A be R . According to the Castigliano's theorem

 


                                           

 

The bending moment at any point X at a distance x from A is given by
