Here’s a way to calculate the reliability for designs with several subsystems. • Weibull plots fit a curve through data, not data to a predetermined distribution’s curve. • After evaluating subsystems ...

An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...

Selecting a set of bearings to withstand anticipated loads is a common design task with power-transmission equipment. Another deals with finding a cumulative component reliability that exceeds the ...
