When the outside temperature is 5.2 ⁰c, a steel beam of cross-sectional area 52 cm2 is installed in a building with the ends of the beam bolted securely to two immovable pillars. in the summer thetemperature of the beam rises to 37⁰c. what is the compressional force fn on the beam? the coefficient of linear expansion of steel 1.1 × 10−5? c−1 and young’s modulus of steel is 2 × 1011 n/m2. answer in units of n.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false

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.
