Description

Torsion occurs primarily on axles and drive shafts in motor vehicles and machines. The torsion
occurring in the shaft cause cross-sections of the shaft to be pushed together around the
longitudinal axis. When a torque is applied to a shaft the cross-section remains flat and no
warpage occurs. In the event of minor torsion the length and radius remain unchanged. The
straight lines on the outer circumference of the shaft running parallel to the axis become
helixes. Non-circular cross-sections mostly result in warpage.
SMT-SM-09 investigates the torsion of a bar under a torque. The bar is clamped into two
movable support blocks by a chuck. The torque is generated by a circular disk, a deflection
roller and a weight.
