The simply supported beam in the Figure has a rectangular cross-section 150 mm wide and 240 mm high. (1) Compute the maximum bending stress in the beam.

(2) Sketch the bending stress distribution over the cross-section on which the maximum bending stress occurs.

(3) Compute the bending stress at a point on section B that is 35 mm below the top of the beam.

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
