A linear relationship exists between the strain ( ϵ ) imposed upon a material type and the corresponding stress ( σ ) needed to cause such a deformation; well, up to a limit : The linear portion of the slope corresponds to magnitudes of strain that will cause a material to flex and snap backContinue reading “SOLIDS: Strength”

SOLIDS: Strain
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 Balanced Wheatstone Bridge
The voltage ( V ) drops across parallel-circuit resistors ( R ) are equal in magnitude; conversely, the currents ( I ) traveling through parallel branches may or may not be the same. For this reason, parallel circuits are sometimes referred to as being current dividers. Take the following diagram into consideration: Since the R1Continue reading “INTRODUCTION TO ELECTRONICS: The Balanced Wheatstone Bridge“
