We’ve all attempted to break an egg by squeezing it with our hands and failed miserably. Like an arch under a bridge, the shape of an egg helps distribute the applied force across the entire surface.  Cracking an egg with the edge of a pan is easy because the force is concentrated on one small section of shell. When force is applied more evenly eggs appear to be much stronger.

An ADMET 7601 single column frame equipped with an eP2 touch panel controller and eccentric roller grips can be used to accurately run ASTM D412 to measure tensile strength and elongation.

This test shows a textile ribbon being pulled apart at a constant rate of speed until it breaks. Measurements include the force required to break the sample and the amount the material stretched before breaking (elongation).
