1. A potentiometer with a total range of 350° is supplied with a voltage of 12 Vdc. Find the output voltage for an angle of 135°.
2. An absolute optical rotary encoder has five tracks. How many bits is the output, and what is the resolution in degrees per state (that is, degrees per LSB)?
3. A toothed-rotor sensor has 30 teeth. Find the rpm if the sensor outputs pulses at 100 Hz.
4. A CK20-B tachometer is mounted piggyback to a motor with a 10:1 built-in gearbox
5. Both optical and Hall-effect sensors can be used as proximity switches. Name one possible application for each.
6. When a 200-lb man gets in his car, the car body sinks 1 in. What is the spring constant for the suspension system of the car?
7. A semiconductor force sensor has a sensitivity of .2 V/lb. If a 3-lb force is applied to the sensor, what would the sensor output voltage be?
8. Construct a temperature sensor using the LM35 with the following specifications: Supply voltage = 12 V, and output = 0.5 V/°C.
