Abstract
An extensometer includes a first element and second element to be set at a predetermined distance apart, with a coupling for setting and holding the two elements at the predetermined distance apart. The coupling is movable by the action of a biasing force to an engaging disposition in which it engages with the two elements to set and hold the two elements at the predetermined distance apart, and the coupling moves under action of the biasing force to a disengaged disposition in which it no longer holds the two elements at the predetermined distance apart upon removal or sufficient relaxation of the applied force.
