Lecture S9 Muddiest Points General Comments Today, we used Laplace transforms to Fnd the impulse response of RC circuits, and also began analyzing aircraft phugoid motion using Laplace transforms. Responses to Muddiest-Part-of-the-Lecture Cards (Only 15 cards) 1. If a circuit isn’t a voltage divider, and you didn’t want to use the loop or node method, how would you Fnd G ( s ) ? (1 student) You wouldn’t. You have to solve the circuit somehow to Fnd the transfer function. 2. Can you go over how to Fnd the transfer function without using tricks like the voltage divider? (1) Sure. Briefly, all you have to do is use the node method. In the example, there was only one unknown node, so it’s not too hard. See me at office hours on Monday, and we’ll do it together. 3. The only thing on the mud card was the following equation: 1 D = ρv 2 SC D 2 (1) The equation above should be a review from fluids. The drag coefficient is always deFned as D C D = 1 ρv 2 S 2 where D is the drag,
