+//R_a+R_c=25 //KN //R_a,R_b are reactions at supports A and C respectively
+L_ab=2 //m
+L_bc=3 //m
+
+//Calculation
+
+//From F.B.D,we get
+//dell_L_AB=(R_a*L_AB)*(A*E)**-1 //Elongation of portion AB
+//dell_L_BC=(R_c*L_BC)*(A*E)**-1 //Compression of portion BC
+
+//After simplifying above equations we get,
+//R_a=(1.5)*R_c //KN
+//R_a+R_c=25 //KN
+//Solving the above simultaneous equations using matrix method
+A=[1 -1.5;1 1]  //Here the coefficients of the first equations of unknowns are setup
