Consider a system with loop transfer function: GH(s) = (s(s + 2))/(s + 1)(s2 + 1). Sketch the Nyquist curve for this loop transfer function and using the Nyquist stability criterion determine the stability of the closed-loop system.
sketch the root locus for teh characteristic equations of the system for whichls s2 ss1s5and determine the value of
Air at 290oC flows over a flat plate at a velocity of 6 m/s. The plate is 1m long and 0.5 m wide. The pressure of the air is 6 kN/2. If the plate is maintained at a temperature of 70oC, estimate the rate of heat removed form the plate.

Truck has a compaction ratio of 1:2. Pickup time is 1.58 min per service. Truck spends 20 min at the disposal site. It takes 35 min to drive to the disposal site. Assume a density of 250 lbs/cubic yard for uncompacted refuse and 500 lbs/cubic yard..
A cylindrical wooden storage vat has a 20 ft outside diameter. It is filled with 24 feet of brine with a specific gravity of 1.06. The wooden staves making up the vat are bound by flat steel bands evenly spaced vertically around the tank.
Sketch the crankshaft, connecting rod, piston, and frame as free bodies when the piston is 60° before head-end dead center on the compression stroke. Sketch the entire compressor as a single free body for this condition.
In an interview for a manufacturing engineering position, you have been told that a certain product was not performing as intended and that changes needed to be made to a few of the features on the component such as shaft sizes and hole dia..
