Torsion of Circular Sections Kit
Model Number: ES5
Explore how specimen length, material, and polar second moment of area affect angle of twist.
Overview
This kit includes different circular section specimens and adjustable chucks for experiments in torsion. Students fix the specimens in the chucks and apply weights to a lever arm. The arm applies a moment (torque) to one end of the specimen. A scale on the arm shows the angle of twist.
Standard tests show the relationship between torsion and ‘J’ (polar second moment of area) value. Students use this to predict the twist angle for any given specimen. The choice of different specimens allows comparisons of different specimen material and how it affects torsion, introducing the Modulus of Rigidity.
Students can also move the chuck positions for easy experiments showing the relationship between specimen length and angle of twist. This versatile kit is part of a series that allows many experiments using different arrangements of their parts. Students, teachers or lecturers fit the parts of the kit to the Work Panel (ES1) (supplied separately) to study or show an engineering science topic.
