1. Find the change in resistance of an electrical resistance strain gauge with a gauge factor of 2.0 and a resistance of 100 Ω when subject to a strain of 0.001.
2. Find the resolution of an analogue-to-digital converter with a word length of 8 bits and an ?analogue signal input range of 10 V.
3. For a system with a transfer function 1/(s2 + 6s + 9) when subject to a unit step input, is the output as a function of time ?underdamped, overdamped or critically damped? Show your work
4. For the displacement of the mass in the basic mechanical system model shown below as a result of the applied force
A First-order with no forcing term.
B First-order with a forcing term.
C Second-order with no forcing term.
D Second-order with a forcing term.
Justify your answer.
5. Write a program for a Raspberry Pi in C to move a DC motor at near max speed when a tilt sensor indicates a substantial tilt in the system. When the tilt goes away, stop the motor. Make this program run f-o-r-e-v-e-r. Please comment throughout the program.
