Answer all questions Question 1 (Long Question) Engineers are often entrusted with the responsibility of implementing large-scale projects involving millions of Ringgit. In view of the large amount of money changing hands, the integrity and ethical standards of engineers are being put to test. What measures can an engineer take to prevent corruption and unethical practice of cutting corners in order to safeguard the good image of the engineering profession? (120 words) Question 2 (Short Questions) Trustworthiness and honesty are two key attributes required of an engineer in his professional conduct. Describe how these two key attributes are related to the following ethical requirements: i. Being truthful. ii. Not withholding information. (b) The following are ethical concerns raised by Conflicts of Interest: i. Potential bias ii. Perceived deception iii. Loss of trust Explain briefly the above ethical concerns in relation to conflict of interest in engineering practices. Please discuss Q1 and Q2 taking into consideration provisions of the IEM / BEM Regulations on Code of Conduct.

In Myers, Montgomery, and Anderson-Cook (2009), an application is discussed in which an engineer is concerned with the effects on the cracking of a titanium alloy. The three factors are $A$, temperature; $B,$ titanium content; and $C,$ amount of grain refiner. The following table gives a portion of the design and the response, crack length induced in the sample of the alloy. $$ \begin{array}{rrrr} \multicolumn{1}{c} {A} & \multicolumn{1}{c} {B} & \multicolumn{1}{c} {C} & \text { Response } \\ \hline-1 & -1 & -1 & 0.5269 \\ 1 & 1 & -1 & 2.3380 \\ 1 & -1 & 1 & 4.0060 \\ -1 & 1 & 1 & 3.3640 \end{array} $$ (a) What is the defining relation? (b) Give aliases for all three main effects assuming that two-factor interactions may be real. (c) Assuming that interactions are negligible, which main factor is most important? (d) At what level would you suggest the factor named in (c) be for final production, high or low? (e) At what levels would you suggest the other factors be for final production? (f) What hazards lie in the recommendations you made in (d) and (e)? Be thorough in your answer.

The circuit shown in Fig. $\mathbf{P 2 6 . 7 4 ,}$ called a Wheatstone bridge, is used to determine the value of an unknown resistor $X$ by comparison with three resistors $M, N,$ and $P$ whose resistances can be varied. For each setting, the resistance of each resistor is precisely known. With switches $S_{1}$ and $S_{2}$ closed, these resistors are varied until the current in the galvanometer $\mathrm{G}$ is zero; the bridge is then said to be balanced. (a) Show that under this condition the unknown resistance is given by $X=M P / N$. (This method permits very high precision in comparing resistors. $?$ (b) If galvanometer G shows zero deflection when $M=850.0 \Omega, N=15.00 \Omega,$ and $P=33.48 \Omega,$ what is the unknown resistance $X ?$
