Torsion of Bars Apparatus Model MT 038
Torsion of Bars Apparatus Model MT 038
Sci-tech Torsion of Bars Apparatus Model MT 038 investigates the torsion of a bar under a torque. The bar is clamped into two movable bearing blocks by a chuck. The torque is generated by a circular disc, a deflection roller and a weight. The clamping length and torque can be varied. The resultant torsion is read-off at two random points on the bar by means of angle indicators.
The fundamentals of elastic torsion are illustrated by the round bar. Three other bars are provided in order to investigate special cases: two thin-walled enclosed sections (a tube and a square tube) and a longitudinally slotted tube (thin-walled open section).

Item Description
Features
* Elastic torsion of a bar1
* Round bar, tube, longitudinally slotted tube and square tube as test bars1
* Indication of the angle of twist at two random points on the bar
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 circular 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.

All the component elements of the experiment are clearly laid-out and housed securely in a storage system. The complete experimental set-up is arranged in the frame.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
