The following truss is subjected to vertical loads of 20 KN at joints E and D. In addition to the loads, support A settles by 5 mm and member AB and BC are subjected to a temperature drop of 50°C. Given Young’s modulus, E = 200 GPa, cross sectional area for each member, A = 500 mm2 and coefficient of thermal expansion of, α = 1.25 x 10-5/°C. Find the internal forces in each member using force method. 20 KN...
