What does Hooke’s Law explain ?

If the external force is larger than the
(1.)size
(2.)volume
(3.)elastic limit
of material, it may result in permanent deformation in the shape and size of the object. This characteristic is known as the
(4.)material behavior
(5.)elastic behavior
(6.)plastic behavior
of an object.

The higher the astm grain-size number, the coarser the grain is. 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

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
