An electrochemical cell is based on these two half-reactions: Ox: Cd(s) ? Cd$^{2+}$(aq, 0.47 mol L$^{-1}$) + 2e$^-$ $E^\circ_{anode}$ = ?0.40 V Red: MnO$_4^-$ (aq, 1.16 mol L$^{-1}$) + 4H$^+$ (aq, 4.5 mol L$^{-1}$) + 3e$^-$ ? MnO$_2$(s) + 2H$_2$O(l) $E^\circ_{cathode}$ = 1.68 V Part A Calculate the cell potential at 25 $^\circ$C. Express your answer to two decimal places and include the appropriate units. $E_{cell}$ = 2.08 V Review your calculations and make sure you round to 2 decimal places in the last step. No credit lost. Try again.

3.11 (B). A steel beam of rectangular cross-section, 100 mm wide by 50 mm deep, is bent to the arc of a circle until the material just yields at the outer fibres, top and bottom. Bending takes place about the neutral axis parallel to the 100 mm side. If the yield stress for the steel is 330 MN/m$^2$ in simple tension and compression, determine the applied bending moment and the radius of curvature of the neutral layer. $E = 207$ GN/m$^2$ Find how much the bending moment has to be increased so that the stress distribution is as shown in Fig. 3.47. [I.Mech.E.) (13.75 kNm; 15.7 m; 16.23 kNm.]

4. Mueller has been approached about providing a new service to its clients. The company will bill clients $160 per hour; the related hourly variable and fixed operating costs will be $70 and $18, respectively. If all employees are currently working at full capacity on other client matters, the per-hour opportunity cost of being unable to provide this new service is: $90. $160. $88. $72. $0. 6. Torrey Pines is studying whether to outsource its Human Resources (H/R) activities. Salaried professionals who earn $390,000 would be terminated; in contrast, administrative assistants who earn $148,000 would be transferred elsewhere in the organization. Miscellaneous departmental overhead (e.g., supplies, copy charges, overnight delivery) is expected to decrease by $35,000, and $26,000 of corporate overhead, previously allocated to Human Resources, would be picked up by other departments. If Torrey Pines can secure needed H/R services locally for $410,000, how much would the company benefit by outsourcing? $15,000. $44,000. $163,000. $192,000. Nothing, as it would be cheaper to keep the department open.
