Sketch the root locus for the closed-loop systems with forward-path transfer function given below. Just do a quick sketch, no need to calculate break-in/break-out point(s) or exact imaginary axis crossing point.(a)G(s) =K(s+ 2)(s+ 6)s2+ 8s+ 25(b)G(s) =K(s2+ 4)s2+ 1(c)G(s) =K(s2+ 1)s2(d)G(s) =K(s+ 1)3(s+ 4)

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

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
