WebbLet us arbitrarily define the singularity zone as the region within which the deviation is less than 20% for the x stress; this represents a value of r/a = 0.02. In other words, the term "singularity zone" is approximately one-fiftieth of the half crack size.

WebbOne of the features of a potentiometer is its variable voltage and ability to hold up multiple resistance values. To reduce the complexity of the circuit, manufacturers reduce the resistance value of the POT into multiples of 10, 20, 22, 25, 47, and 50. As a result, some popular potentiometer values are 10k ohms, 1k ohms, 5k ohms, and 100k ohms.
