The state of stress at a point in a solid is given as 10 5 5 7 xy MPa. Consider a plane passing through this point with normal vector n = (1/ √ 2)ex + (1/ √ 2)ey. What are the normal and shear stresses on this plane?

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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.
