Sketch the root locus plot for the open loop system given with transfer function 13s2+12splaced with a proportional controller in unity negative feedback loop. Use Kp as your root locus parameter. Determine the smallest time constant possible for the closed loop

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
