//Consider Equilibrium of joint A
//As there are no Load applied at A members AC and AB have nothing to Balance 
//So they are null members
F_AB=0
F_AC=0

//Consider Equilibrium of joint B

//Applying the summation of horizontal forces  we get
F_DB=4*(cos(45*%pi*180**-1))**-1

//Applying the summation of vertical forces  we get
F_BC=F_DB*sin(45*%pi*180**-1)

//Consider Equilibrium of joint B

//Applying the summation of vertical forces  we get
F_CE=4*(sin(45*%pi*180**-1))**-1

//Applying the summation of horizontal forces  we get
F_DC=F_CE*cos(45*%pi*180**-1)
