Given the following LP model, using Solver
Min 3S + 9C
s.t.
6S + 10C <=60
7S + 5C <= 42
X , Y >= 0
a. What is the optimal value of the objective function?
b. What are the optimal values of the two decision
variables?
c. Find the range of optimality for objective function
coefficients S and C.
d. How would a decrease of 1 gram in the S coefficient of the
objective function affect the optimal values...
?(?) = (? + 5)/[s(s+2)(s^2+6s+10)]
Sketch the root locus by hand. You may verify your sketch using
MATLAB but you must show sufficient intermediate work for
sketching.
Use MATLAB to identify the proportional controller value (to the
tenth decimal point) that would cause your system to be unstable.
Be sure to show evidence of this value. Plot your system response
due to a step input for this controller.
1. Antimony reacts with sulfur according to the following reaction:2Sb(s) + 3S(s) → Sb2S3(s)What is the mass percent yield from 2.57 g of Sb in excess S, if 1.72 g of Sb2S3 is obtained? Sb2S3 is 340. g/mol
2. For the following reaction at 25 oC, ΔHo = -1667 kJ and ΔSo = 184 J/KA +4B → 3C + 3D What is ΔGo at 238 oC in kJ?
Consider the unity feedback negative system with an open-loop
function G(s)= K (s^2+10s+24)/(s^2+3s+2).
a. Plot the locations of open-loop poles with X and zeros with O
on an s-plane.
b. Find the number of segments in the root locus diagram based
on the number of poles and zeros.
c. The breakaway point (the point at which the two real poles
meet and diverge to become complex conjugates) occurs when K =
0.02276. Show that the closed-loop system has repeated poles...
From 1+K*L(s)=0
L(s) = 1/((s+1)(s+2)(s+10))
Solve for gain K where the root locus passes through
the damping ratio. z=0.176. With out Matlab. Please show all
work.
Note: I know we need to use some trig and the
magnitude criteria but u cannot seem to figure it out. Thank
you!
