Explain and discuss why engineers usually want the minimum variance unbiased estimator (mvue). what benefits are achieved by using the mvue in making engineering decisions, and what risks or impacts might be seen if another estimator is chosen at times? try to use hypothetical examples to illustrate your thinking.

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

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
