b) Analyse the truss shown in Fig. 4 (with active global coordinates, as shown) ஊம்‌ (10)
find the joint displacements, support reactions and bar forces. The truss is subjected
to direct loads Fl = 50 kN; F2 ಎ 30 kN, and a lack of fit due to bar AC being too
long by 5 mm. Assume all bars to have same axial rigidity AE = 6000 KN. Use

stiffness matrix method.
