Problem 1 (Formulation): 20pts For the composite stepped rod below, (a) determine the tip displacement at the 100-k force end by modeling the rod using two prismatic truss elements connected in series. Use the truss prismatic element stiffness matrix given below. (b) derive a stiffness matrix for the stepped composite truss member with only 2 nodes at the ends of the stepped member (no node in the middle) using the direct stiffness approach.
