1 ECE 313 (Spring 2009) Homework #3 (Due: February 9, 2009, Monday, in class) Reading Assignment Reminder: Section 2.8, Section 5.1 – 5.2 Recommended Optional Reading: Section 2.10 – 2.11 Problems: 1) (10 pts) The following figure shows a motor driving a load and also the torque-speed curve for the motor. 1 J and 2 J denote the moments of inertia of the motor and the load, respectively; 1 N and 2 N denote the numbers of gear teeth; 1 D and 2 D denote the constants of viscous friction for the motor and the load, respectively. Find the transfer function, ) ( ) ( ) ( s E s s G a L . Your final answer should include any variables but s . 2) (10 pts) A loudspeaker is an electromechanical system where an electrical signal v is converted into mechanical motion of a membrane, which generates sound. It can be modeled by the electric circuit and mechanical system shown in the following figure. The (induced)
