We have seen how the spring constant ( k ) varies in proportion to the magnitude of force ( Fs ) acting within a springy system. Consider the two systems below, where three physically identical spring systems are used to create two systems, one on the left with the other to the right of theContinue reading “SOLIDS: Strain”

INTRODUCTION TO ELECTRONICS: The Unbalanced Wheatstone Bridge and Sensor Technology
A transducer is an electronic device that measures physical parameters such as mechanical strain, pressure, optical density, and/or temperature. If temperature is being measured, an instrument called a thermistor acts as a variable resistor at the R1 location of a Wheatstone bridge. At a known neutral temperature, a zero reference voltage ( Vout ) valueContinue reading “INTRODUCTION TO ELECTRONICS: The Unbalanced Wheatstone Bridge and Sensor Technology“
