4. For a truss system composed by 4 bars, the section of each bar A=100mm, the elastic modulus E=29.5*10 N/mm2. A transverse force F=20000N is applied at Node 2 and a vertical force F=-25000N is applied at Node 3. (This question is optional) 74 25000N 23 114 1/3 300mm 20000N 400mm I (1) Calculate the length, cos(©) and sin(e) for each bar element. (2) Find the element stiffness matrices. (3) Find the equivalent nodal force vectors if needed (4) Assembly the global stiffness matrix with the force vector (5) Apply BC and solve the system
