Apparatus for Testing Torsion and Deflection

Technical Description

This table unit covers a wide range experiments on bending and torsion. Two bearings can be slid along the steel base section as required and attached to it via threaded holes. The bearing arrangement provides different ways of clamping the ends of the bar. This allows different bearing conditions to be demonstrated. The amount of deformation is determined using a position measurement gauge. This is equipped with a magnetic base and can be attached at any point along the base frame. Two drill chucks retain the test bars securely for torsion experiments. Clamping lengths of up to 600mm are possible. A weight set of up to 20N is used to apply loads. The torsion moment is applied with a lever mounted in ball bearings.

Learning Objectives / Experiments

· Deflection of bar loaded with weights as a function of :
- loading force
- bar material and its modulus of elasticity
- section width and section height
- bearing spacing
· Comparison of the bending stiffness of different sections for the same cross-sectional area
· Comparison of cantilever beams and beams on two supports
· Determination of the modulus of elasticity in shear for different materials
· Relationship between torsion angle and clamping length on torsion
· Relationship between torsion angle and torsion moment
· Relationship between torsion angle and bar cross-section

Features

· Measurement of basic deformation relationships on bending and torsion
