Q1/ The assembly consists of two 10-mm diameter steel rods AB and BC, and a rigid bar B. After applying the loads shown, determine: (1) The maximum normal stress developed in each rod. (2) The horizontal displacement of end C with respect to the fixed support at A. (3) Suppose that only rod BC is exposed to change in temperature, what would be the change that keeps point C in the original position. Use Est = 200GPa, st= 12(10)-6 600 mm 400 mm 50 kN 40 kN А В 50 kN

Equilibrium and Support Reactions

Civil engineers deal with structures that are composed of several members connected or with individual members such as beams and columns. To analyze such structures, the condition of statics must be applied. Under the static condition, the members are considered to be in equilibrium under the action of forces, that is, the members are assumed to be having negligible velocity.
