15. A locomotive is tested with a dynamometer car coupled between the tender and the train. Traveling over a level track at a speed of 130 kmply,the dynamometer registers 10615 kg. What horsepower is the locomotive then delivering? On an extended run the dynamometer integrator gives 2945 kw hr, and over the same stretch 6215 kg of 27920 J/g coal were consumed. Calculate the thermal efficiency of the locomotive.

Problem 2 A major automotive company wants to use wind tunnel experiments to estimate the aerodynamic drag coefficient of one of their new automobile designs. They believe that the drag force, F, is related to wind speed, v, by the following relationship F = pCaAƒv², where p is the density of air at standard atmospheric conditions, Af is the frontal area of the vehicle, and Ca is the drag coefficient. It is common in the automotive industry to estimate CaAf as a single, lumped parameter. The table below shows the outcomes of the company's wind tunnel experiments. Please note that the force measurements include measurement noise. Wind speed, v (m/s) | Drag force, F (N) 10 5 10 70 15 120 20 210 25 330 Part a Use the slope estimation formula to estimate CaAf for the above automobile design. Assume that the density of air is p = 1.2kg/m³. Please note that in order to use linear slope estimation, you need to be careful about what you define/choose to be your regressor.

Part 2 Set up a spreadsheet solution to this problem. This will require that you derive one formula to express the relationship between the friction coefficient, the spring constant, and the spring compression; and a second formula to find the cost of using different slide and spring types. Set up your spreadsheet as shown below. You can fill in the "Acceptable?" column manually, rather than using a formula.
