A unity feedback system has a transfer function G(s) = K/(s+1) where K= 2 is subjected to unity step input. A PD-controller is added where Gc(s) = 500+0.5s. determine the steady state error before and after adding the controller respectively. Immersive Reader

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

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.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
