An emergency shoring for the construction of the bridge in between train traffic requires to have a temporary 20 feet column without bracing, and the vertical capacity is unknown. use a w14x74 (a992) section with both ends connected with pins. using the aisc-lrfd manual the properties are rx=6.04" and ry=2.48", whereas ag=21.8 in2 . what is the value of pu we can guarantee the railroad our column will resist? remember that they can’t afford to have a derailment or excessive movement with your solution.

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.
