<p></p> <p><b>New page</b></p><div>&lt;b&gt; Q: &lt;/b&gt;<br /> Are the q_1 and q_2 functions of time or some kind of absolute position? <br /> <br /> &lt;b&gt; A: &lt;/b&gt;<br /> I&#039;m assuming that this question referred to the spring mass system found on p. 5 of the lecture notes.<br /> <br /> In this case, q1 and q2 give the positions of the masses, and as such are going to be functions of time.<br /> <br /> The state of this system, X, is represented by the positions and velocities of the two masses [q1, q2, q1_dot, q2_dot], <br /> and we are trying to set up the equation that will give dX/dt in terms of elements of X. If we were to solve this system of equations, we&#039;d then get q1 and q2 as functions of time and the initial conditions.<br /> <br /> --[[User:Lindzey|Lindzey]] 18:19, 2 October 2006 (PDT)<br /> <br /> [[Category:CDS 101/110 FAQ - Lecture 2-1]]</div>
