1.Two steel rods with fixed supports at A and C are attached by a rigid flange at point B and a downward load of 120 kN is applied to the flange. The upper rod has a cross section of 800 mm^2 and the lower rod has a cross section fo 1,600 mm^2. If the modulus of elasticity is 200 GPa determine the normal stress in each rod. Show all work.

2.The bent road has an E=200 GPa, G=75 GPa, and a radius of 30 mm. Use Castigliano's theorem and determine the vertical deflection at C. Include the effects of bending, shear, and torsional strain energy.
