1 Introduction On the modern bar and wire mills inter-stand tension is controlled at rolling [1, 2] For a variety of reasons, it is impossible to use tension direct control systems that is why tension value is inferred by the rolling motor torque...

Tension, Compression, Shear and Torsion

Tension Tension stress (or tensile stress) occurs when two forces pull on an object in opposite directions so as to stretch it and make it longer and thinner The primary load a muscle experiences is a tension load When the muscle contracts it pulls on the tendons at both ends, which stretch a little So the tendons are under tensile stress...
