Assessment Criteria The work will be assessed by comparison with an approved marking scheme. Fully correct solutions will receive the number of marks indicated. Marks will be reduced for errors in proportion to their severity. You need to indicate the units for all electrical quantities. You need to clearly present the equations used for calculations and the comparison results.

Fuel Tank A float system is used to measure fuel in a gas tank. The float is connected to a gear and the gear is connected to a rotary potentiometer. This is shown in the corresponding figure. Potentiometer shaft 6 teeth 30 teeth 1.21. Empty Full Half Float The rotary potentiometer is linear with a resistance, R=100kn, distributed over a 330° strip (i.e. the potentiometer can rotate 330°). The float is connected to the shaft of a gear with 30 teeth and that in turn rotates the potentiometer through a gear with 6 teeth. The mechanical linkage is set so that when the tank is full, the potentiometer resistance is zero. The float is shown in three positions to show how the resistance changes (increases from zero at full tank). 1. Estimate the cost of a linear rotary potentiometer for this application?
