Q.1. A plane truss is loaded and while solving for internal forces in truss members we are able to formulate the ten equations given below: Ax +AD =0; Ay +AB =0; 74+ BC+(3/5) BD =0; -AB (4/5) BD = 0; -BC +(3/5) CE = 0; -24-CD- (4/5) CE =0; -AD+DE-(3/5) BD = 0; CD + (4/5) BD =0; -DE-(3/5) CE =0; Ey + (4/5) CE=0; Ax, Ay and Ey are support reactions, while the letters BC, CD etc. represent the internal forces in corresponding truss members. Solve for all unknown forces using MATLAB. Hint: Solve by the matrix method for simultaneous linear equations
