33. A drug is injected into a patient's bloodstream. The concentration of the drug in the bloodstream \( t \) hours after the drug is injected is modeled by the formula \[ C(t)=\frac{0.12 t}{t^{2}+t+1} \] milligrams per cubic centimeter. Estimate the change in concentration over the time period from 30 to 35 minutes after injection.

a) A simple system is represented by a block diagram illustrated in Figure Q4(a) below. Based from this system, find the number of poles in the left half-plane, the right half-plane, and on the $j\omega$-axis for the system below. Evaluate the stability of the system. $R(s)$ \(\to\) $\frac{200}{s^4 + 3s^3 + 30s^2 + 30s + 200}$ \(\to\) $C(s)$ Figure Q4(a) (CO2: PO2 \textendash{} 10 Marks) b) Lasers can be used to drill the hip socket for the appropriate insertion of an artificial hip joint. The use of lasers for surgery requires high accuracy for position response. Consider the system shown in Figure Q4(b) which uses a DC motor manipulator for the laser. $R(s)$ \(\to\) \(\boxed{K}\) \(\to\) $\frac{1}{0.02s(s^2 + 15s + 50)}$ \(\to\) $Y(s)$ Figure Q4(b) Based on the Figure Q4(a), answer the followings. I. Evaluate the system type. (CO2: PO2 \textendash{} 3 Marks) ii. Design the amplifier gain K so that the steady-state error for a ramp input, $r(t) = At$ (where $A = 1$ mm/s) is less than or equal to 0.1 mm. (CO2: PO2 \textendash{} 6 Marks) iii. Using Routh Hurwitz table, find the range of amplifier gain K, for the system to be stable. (CO2:PO2 \textendash{} 6 Marks)
