2. (2 points) Locate the centroid and calculate the moments of inertia for a “T” shaped beam that consists of a stem (the upright piece) that is a “2x8” and the flange (the piece across the top) that is a “2x6”, centered on the stem. Note that a “2x6” has actual dimensions of 1-1/2”x5-1/2” and a “2x8” has actual dimensions of 1-1/2”x7-1/2”.

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.
