A system plant has a transfer function as follows: Y(s)/U(s) = (s+4)/(s+2)^3
(a) Obtain the state space representations in controllable, observable, and Jordan canonical forms for
this control system. In other words, develop state equations in the form X* = AX +BU
and
Y = CX + DU
(b) Using the Jordan matrix for the above system, find out the state transition equations, and find out
system output for step input.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

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

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
