Problem $1()$

For the compound beam and loading shown and considering that the supports at A and C are rollers, the support at E is a pin and the connection B is a pin:

Determine the support reactions at $A,C$ and $E$ and the internal forces at connection $B.($a$)$

Draw the shear and moment diagrams including maximum and minimum values and the shear force and bending moment values at points $A,B,C,E$ and F $.$
