Stiffness Bending and Torsion

Product Description

Description:

A compact bench-mounting frame that holds different partsfor investigations into stiffness of materials. The standard includes parts fortests in bending of beams of different materials and cross-section. Optionaladditional kits allow investigations into different beam fixings and torsionalstiffness. The main part is a rigid metal frame. Supplied as standard are twoadjustable knife edges that work as simple supports for test beams. A linearscale on the back panel of the frame allows accurate positioning of the knifeedges. The kit also includes weights, a magnetic dial gauge and a set of differentbeams. Also included in the standard kit is a vernier gauge for students toaccurately measure dimensions of the specimens they test. Students add differentloads to the beams using weights on a hanger. The dial gauge indicator on theback panel accurately measures beam deflection. The Additional ExperimentationKit available as an optional extra, enables further investigations into asimple cantilever, a propped cantilever and an encastre beam. The AdditionalTorsion Testing Kit is also available as an optional extra. It allows torsiontests on solid rods of different materials and a tube.
