Torsion Testing Machine

Product Description

Torsion Testing Machine, for rods : 

INTRODUCTION:  
A system of loading which causes section of a bar or shaft to rotate about its central longitudinal axis relatively to another such section and which thus produces twist or torsion in the bar, constitutes a torsional load. The load may be composed of forces acting in any direction but the twisting or torsional affect is provided by the couples formed by these forces in planes normal to the central axis. The torsional shearing stresses in circular cross section vary from zero at the axis of the section to a maximum value at the extreme fibres. If no bending is present pure shear exists. Torsion Testing machine Consists of two independent chucks.
