Description
A compact, bench-mounting frame that holds diff erent parts for investigations into stiff ness of materials. The standard TE16 includes parts for tests in bending of beams of diff erent materials and cross-section. Optional additional kits allow investigations into diff erent beam fi xings and torsional stiffness.
The main part is a rigid metal frame. Supplied as standard are two adjustable knife edges that work as simple supports for test beams. A linear scale on the back panel of the frame allows accurate positioning of the knife edges. The kit also includes weights, a magnetic dial gauge and a set of diff erent beams. Also included in the standard TE16 kit is a vernier gauge for students to accurately measure dimensions of the specimens they test.
Students add diff erent loads to the beams using weights on a hanger. The dial gauge indicator on the back panel accurately measures beam deflection.
The Additional Experimentation Kit (TE16a), available as an optional extra, enables further investigations into a simple cantilever, a propped cantilever and an encastre beam.
The Additional Torsion Testing Kit (TE16b) is also available as an optional extra. It allows torsion tests on solid rods of diff erent materials and a tube.
Learning outcomes
Standard TE16 Kit:
• Investigation of the stiff ness in bending of diff erent materials of the same cross-section (Young’s modulus/ stiff ness)
• Investigation of the stiff ness of a single material with diff erent cross-section geometries (second moment of area, or I value)
When used with the optional TE16a:
• Experiments to fi nd the defl ected shape of a beam and bending of a beam clamped at one end (a cantilever).
• Comparison of a simply supported beam, a cantilever and an encastré beam.
When used with the optional TE16b:
• Experiments to fi nd the relationship between angular defl ection and the dimensional and material properties of rods and tubes (torsional stiff ness).
