Three bars are connected with smooth pins to form the frame shown. End B of the horizontal member BDF consists of a pin that can slide freely (no friction) in the slot of member AC. The weights of the bars are negligible. Determine the reactions at supports $\mathrm{A}$ and $\mathrm{E}$. Determine the reactions at joints $B,C$ and $D$.
