Question A1 Set up an amortization schedule for a $25,000 loan to be repaid in equal instalments at the end of each of the next 3 years. The interest rate is 10% compounded annually. (Total 6 marks) Question A2 Simon recently received a credit card with an 15% nominal interest rate. With the card, he purchased a new notebook for $9,888. The minimum payment on his credit card is only $200 per month. If Simon makes the minimum monthly payment and makes no other charges, advice Simon the number of months it will be for him to pay off the credit card balance. Round to the nearest month. (Total 6 marks) Question A3 Christy just won the Mark Six. She must choose one of the following three award options. Option 1: receive a lump sum today of $65 million Option 2: receive 10 end-of-year payments of $9.5 million Option 3: receive 30 begin-of-year payments of $5.5 million Required: a. If she thinks she could earn 7% annually, advise her which option she should choose. (2 marks) b. If she expects the interest rate will increase, advise her which option she should choose.

Modelling and simulation of the swinging pendulum. Modelling. Determine the mathematical model of the swinging pendulum system differential equation consisting of mass $m = 0.036$ kg, attached to a string of length $L = 0.364$ m, with the mass initially suspended at an angle of $\theta = \frac{\pi}{6}$. Use the gravity as $g = 9.81$ m/s, the damping force coefficient as $f_v = 0.00142$ kg/s, and the inertia as $J = 1$ kg m$^2$. From the obtained model present a general solution of $\delta\theta(s)$ in terms of $m$, $L$, $f_v$, $J$, and $g$. Simulation. Use the software e.g. (Wolfram SystemModeler) to simulate the swinging pendulum system using the above-given paraments and provide the following from the results: \begin{itemize} \item Plot the graph of angular acceleration versus time for a dumped system. \item Determine the settling time of the system from the graph. \item Calculate the natural frequency of the system. \item Calculate the damping ratio of the system. \item Explain whether the system is underdamped and overdamped. \end{itemize} Full Marks: 100

4a. Figure Q4a shows four strain gauges which are mounted onto a cantilever. Given that the strain gauges are placed exactly halfway (x=0.51) along the cantilever and the cantilever is subject to a downward force F=0.5 N, answer the following questions: i. Determine the strain $\epsilon$ for all four strain gauges. [3 marks] ii. The strain gauges are connected in a wheatstone-bridge circuit with voltage supply $V_s$ and the output voltage $V_2$. Draw the Wheatstone- bridge circuit and indicate how each resistor $R_1$, $R_2$, $R_3$ and $R_4$ are connected to the Wheatstone bridge [2 marks] iii. Calculate the resistance values for $R_1$, $R_2$, $R_3$ and $R_4$ [4 marks] iv. Determine the output voltage of the Wheatstone-bridge $V_2$ if the bridge supply voltage $V_1$ = 15V. [4 marks] 4b. Cantilever data: Strain gauges data: Length $l$=25 cm Width $w$=6 cm Gauge factor G=2.1 Thickness $t$=3 mm Unstressed resistance $R_0$=120$\Omega$ Young's modulus E= 70 x $10^9$ N/m$^2$ Strain for strain gauges on cantilever: $\epsilon$ = $\frac{6(l-x)F}{wt^2E}$ Figure Q4a: cantilever with 4 strain gauges The sensitivity of a third stage device in a pressure measurement system is 0.500 V/N. The accuracy of the instrument is specified as: $\pm$0.5% FSD or $\pm$1% of the reading, whichever is greater. When Force is applied to the system, the instrument displays 11.3 V on the 30V range. i. What is the range of the applied Force? [3 marks] ii. The sensitivity of the measurement system is then changed to 0.750 V/N and the voltmeter is switched/changed to the 15V range.
