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)

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
