3. (3 points) For the composite solid shaft comprised of the 120 mm- diameter Shaft AB and the 30 mm-diameter shaft BC, both of which are made of the same material, state the compatibility condition (with proper subscripts) and determine the support reactions at the fixed supports A and C if the shaft is loaded with F-8 kN and given the lengths a-14m and b-5 m. Assume the shaft's material does not leave the elastic range. Co. 12o b S B 0103 0.5F C 0.5F a 3.
