Figure Q2 shows a statically determinate plane truss subjected to a horizontal concentrated load at B. The truss is made using steel with Young's modulus of 205 GPa, and the cross section area for all members are constant. If the horizontal displacement at B is limited to 10 mm, determine the minimum cross section area required for the truss. The solution can be based on Method of Conservation Energy or Method of Virtual Work. (а) (b) Based on Q2(a), suggest an appropriate steel bar measurement.
