What parameters limit the frequency of the motor? List 3 things you might do, if you want the motor to run faster.
1) Lesser windings on the motor as lesser flux is cut and hence more speed
2) The speed of a DC motor can be increased by field weakening. Reducing the field strength is done by inserting resistance in series with a shunt field, or inserting resistances around a series-connected field winding, to reduce current in the field winding. When the field is weakened, the back-emf reduces, so a larger current flows through the armature winding and this increases the speed. Field weakening is not used on its own but in combination with other methods, such as series-parallel control.
3) In a circuit known as a chopper, the average voltage applied to the motor is varied by switching the supply voltage very rapidly. As the "on" to "off" ratio is varied to alter the average applied voltage, the speed of the motor varies

The motor has a knob to control its frequency. You want to have the motor moving "in phase" with the glider t should be pushing to the left when the glider is moving to the left and so on. It will take a while to get this right, so be patient! The alignment doesn't need to be perfect, just close. Start the glider with a large amplitude and let it go with the motor running. Using the motion sensor, observe...
What are apples good strategies? How might you do things differently if you were in charge of making decisions for this firm?
3. What Collection Framework classes can and can't do. Which of the following things can be done by collection classes (List, Set, or Map)? If you can do it, outline how, mentioning relevant methods, else say that it is impossible and why. A program is designed to have a TreeMap<Customer, String>, but Customer has no compareTo method. Is it possible to get the TreeMap to work without changing Customer.java? You have a Map of Strings to Integers. You want to make...
