A simply supported truss is shown below. There is a pin support at A and a roller support at E$.$ Determine the support reactions and the internal force in each member. Use the method of joints. $(25$ pt $)$

$(1)$ Draw Free body diagram of the whole truss $(5$ pt $)$

$(2)$ Use Equilibrium law to find reactions $(10$ pt$)$

$(3)$ Isolate a joint

$(4)$ Draw Free body diagram at a joint $(15$ pt$)$

$(5)$ Use Equilibrium law to find the member forces $(15$ pt$)$

$(6)$ Draw force summary diagram $(5$ pt$)$
