Question

Consider the rigid L-frame KDQC shown, supported by axial members CM and QT and pin support D as shown. Bars CM and QT are made out of steel with a young's modulus of 200 GPa and a coefficient of thermal expansion of 12.4 x 10^(-6)/C. Furthermore, both bars have a cross-sectional area of 1200 mm^2. If the assembly is loaded by a 0.2 kNm concentrated moment as shown and the entire system is cooled by 20C, determine the internal forces in members CM and QT, and the displacements of K,Q, and C.
