    The looser sense puts the force outside the body rather than inside it, such as the pull on a cable or traffic crossing a bridge. Engineers often call this a load and keep stress for the internal force per area. In ordinary technical writing the two meet: an applied stress produces internal stresses.

Origin

The word comes from a shortening of Middle English 'destresse', borrowed from Old French 'destrece' and ultimately from Latin 'distringō' ('to stretch out'). It probably merged with Middle English 'stresse', from Old French 'estrece' ('narrowness') and Latin 'strictus' ('narrow'). The 'mental strain' sense was used occasionally by researchers such as the physiologist Walter Cannon in the 1920s and 1930s, and the 'biological threat' sense was used by endocrinologist Hans Selye by metaphor with stress in physics, becoming popular in the 1950s.
