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.

On a average work day more than work place firs are reorted

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

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
