Each of the variables listed in Problem 1.7 can be brought under feedback control. Describe an actuator that could accept an electrical input and be used to control the variables listed. Give the units of the actuator output signal.

Problem 1.7

Feedback control requires being able to sense the variable being controlled. Because electrical signals can be transmitted, amplified, and processed easily, often we want to have a sensor whose output is a voltage or current proportional to the variable being measured. Describe a sensor that would give an electrical output proportional to:

(a) Temperature

(B) pressure

(d) flow of liquid along a pipe (or blood along an artery) force

(e) linear position

(f) rotational position

(g) linear velocity

(h) rotational speed

(i) translational acceleration

(j) torque
