For the aluminum bar shown in the figure below: Draw the axial force diagram in terms of A, Determine the reactions, Ag and D Draw the axial stress, axial-stran, and axial displacement diagrams using your calculated values for A, and D . The cross-sectional area between A and C is equal to 2 in2. The cross-sectional area between C and D is equal to 4 in. E (aluminum) = 10,000 ksi 20 k 40 k A B с D 6 12" 6" A = 2 in2 A = 4 in 2 Az = k D = k
