Alaminated plastic beam of square cross section is built up by gluing together three strips, each 10 mm 3 30 mm in cross section. the beam has a total weight of 3.6 n and is simply supported with span length l 5 360 mm. considering the weight of the beam (q), calculate the maximum permissible ccw moment m that may be placed at the right support.
(a) the allowable shear stress in the glued joints is 0.3 mpa.
(b) the allowable bending stress in the plastic is 8 mpa

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
