Prof Raghuveer Parthasarathy University of Oregon Fall 2007 Physics 351 Vibrations and Waves List of things to study for the Midterm Exam NOTE This list is intended only as an approximate guide to the topics with which you should be familiar in preparation for the upcoming exam There will cerminly be topics listed here that are not present on the exam And of course this list won t spell out exactly everything that will show up in the midterm 7 it is meant only as an approximate guide Format of the exam The exam in class Wed Nov 7 will be closed book closed notes no calculators and 50 minutes long Some information will be supplied to you see below General advice Study your homework assignments lecture notes and the textbook Chapters 14 Be sure to study the posted solutions to homework problems you didn t understand Understand the derivatiom of everything not just the results Understand the general properties of oscillating systems Some topics Be familiar with Taylor expansions 7in general and especially for common functions like 6 sinx etc Be familiar with basic trigonometry Any necessary identities eg sinAB will be provided Be familiar with dimensional analysis and of course know how to check the dimensional accuracy of anything you derive Be familiar with the complex exponential method for solving differential equations for oscillators Be able to derive the equations of motion of simple pendulum and mass7on7a7spring systems Be familiar with the basic properties of springs 7 extension force energy etc Know how frequency period and angular frequency are related Be able to analyze the vibrations of other oscillators covered in the course electrical circuits oating objects etc Voltage drops across resistors inductors and capacitors will be given to you if needed Damped aidglam Understand the quality factor Q and how it is de ned Know how amplitude and energy decay with time Know remember conditions for over under and critical7dainping Understand the derivation ofxt and be familiar with the form ofxt for underdamped oscillators Know the properties of forced oscillators 7 eg what the amplitude phase and power absorption curves look like as functions of frequency Equations for AOJ 50 and will be given to you if needed you don t have to memorize them Know how to analyze the frequency of oscillation about equilibrium for objects subject to arbitrary potential energy functions Initial conditions 7 be able to determine xl for a system given the appropriate initial conditions
