If a person contracts pneumonia, inflammation occurs in the lobules of the lung, causing fluid leakage into the alveoli. Which of the following best describes the effect this has on gas exchange. Fluid leaks into the pleural cavity and causes a restriction in lung expansion as well as reducing lubrication on the parietal surface of the membrane. The distance between the alveolar cell layer and the capillary endothelium in the respiratory membrane increases to a point at which the surfaces are too far away for efficient gas exchange. The diaphragm and accessory muscles have to work too hard to expand the lungs. Therefore, they become fatigued. When this happens, the person can no longer breathe. As the alveoli fill with fluid, air cannot reach the alveolar surface and gas exchange cannot occur, compromising the function of the respiratory membrane.

Sheridan Company uses a flexible budget for manufacturing overhead that is based on direct labour hours. The variable manufacturing overhead costs per direct labour hour are as follows: Indirect labour $1.10 Indirect materials 0.70 Utilities 0.40 Fixed overhead costs per month are as follows: supervision $3,600; depreciation $1,800; and property taxes $800. The company believes it will normally operate in a range of 7,700 to 11,000 direct labour hours per month. Prepare a monthly flexible manufacturing overhead budget for 2022 for the expected range of activity, using increments of 1,100 direct labour hours. (List variable costs before fixed costs.)

Q19. A cylindrical steel bar, 25 mm in diameter and 3.0 m long, is subjected to an axial tensile load of 50 kN applied at the ends of the bar. Determine the radial (transverse) contraction in the cross section, expressed as a strain value in decimal format, of the steel bar under this axial loading condition. $E_{steel} = 210 kN/mm^2$ and take Poisons ratio as 0.3 \begin{tabular}{|c|c|c|c|c|} \hline A & B & C & D & E \\ \hline $1.5 \times 10^{-4}$ & $5.1 \times 10^{-4}$ & $3.8 \times 10^{-4}$ & $1.5 \times 10^{-2}$ & $3.8 \times 10^{-6}$ \\ \hline \end{tabular}

B. Three high-strength concrete poles, with an effective cross-sectional area of 40,000 mm$^2$ and a length of 2 m, support a stiff steel plate. The center post is 1 mm shorter than the others before the load P is applied. If the concrete's allowed compressive stress is 20 MPa, calculate the maximum load that can be carried. E = 30 GPa for concrete. (15)
