Abstract

A test strand is mounted between a driver and force transducer, and a lever arm connects the driver end of the strand to an elongation (i.e. displacement) transducer. A manually operated switch connects either the resulting force signal or elongation signal to control circuitry of the driver e.g. an operational amplifier, which also receives a programming signal from a function generator which varies the force or elongation applied in accordance with a preset force or elongation programme, e.g. to keep the rate of force or elongation increase constant.
