The bar da is rigid and is originally held in the horizontal
position when the weight w is
supported from c. if the weight causes b to be displaced downward
0.025 in., determine the
strain in wires de and bc. assume that the wires bc and de have an
area of 0.002 in2, and
e = 29,000 ksi.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

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
