Both portions of the rod ABC are made of an aluminum for which E = 70 GPa. Given: P = 4.5 kN. Problem 02.019.a - Deformations in a stepped shaft loaded in tension and compression Determine the value of Q so that the deformation at A is zero.

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
