Q1. A 346-, uniform, 1.04- bar is suspended horizontally by two vertical cables at each end. Cable A can support a maximum tension of 506.0 without breaking, and cable B can support up to 436.0. You want to place a small weight on this bar. What is the heaviest weight you can put on without breaking either cable?

Q2. Air moves through the human trachea at 2.9 m/s during inhalation. Imagine that a constriction in the bronchus exists that the speed doubles. By what amount (in Pa) does the air pressure change as it flows by the constriction? Treat the air as an ideal fluid, and take the density of air to be 1.2 kg/m3. (Hint: does pressure increase or decrease? Also, please give your answer in Pa.)
