The mechanical properties of a metal may be improved by incorporating fine particles of its oxide. given that the moduli of elasticity of the metal and oxide are, respectively, 60 gpa and 380 gpa, what is the (a) upper-bound, and (b) lower-bound modulus of elasticity values (in gpa) for a composite that has a composition of 33 vol% of oxide particles.

The higher the astm grain size number, the finer the gran is. a)-true 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.

What is the correct way to measure the overall length of a boat? measure from the tip of the bow to the highest point on the gunwale. measure from the tip of the bow in a straight line to the stern of the boat. measure from the tip of the bow in a straight line to the back seat. measure from port to starboard at the boat's widest point.
