1.The composite bar consists of a 20mm diameter A-36 steel segment AB (Es=200GPa) and 50mm diameter red brass C83400 (Eb=101GPa) end segments DA and CB. Determine the displacement of A with respect to B due to the applied load.
2.The tapered member is fixed connected at its ends A and B and is subjected to a load P = 7 kip at x =30in. Determine the reactions at the supports. The material is 2in. thick and is made from 2014-T6 aluminum (Eal = 10,600ksi).
