WP 502

Torsion Testing Machine, 100 Nm manually operated

Technical Description

Using this unit, metal test bars are twisted to destruction. The test moment and the angle of twist are recorded during this process. Test bars made of different materials with varying lengths are included. The test moment is applied manually using a hand wheel and a worm drive. Measurement is performed with a strain gauge torsion shaft, the deformation of which is compensated. The measurement can be read off directly in Nm on a digital display on the measuring amplifier. The dolly on the rigid frame can be slid to adapt to different length specimens. Using a calibration device a defined torque can be generated at the start of the experiment. The angle of twist is determined using a graduated scale and and a revolutions counter. Commercially available 1/2" square drive sockets, 17mm across flats, are used as specimen holders.
