Stiffness of Materials and Structures — MOE Lab Tender Details

Stiffness of Materials and Structures

Bench-mounting apparatus enabling a variety of investigations into material stiffness.

Experiments
Investigation of the stiffness in bending of different materials of the same cross-section (Young’s modulus/stiffness)
Investigation of the stiffness of a single material with different cross-section geometries (second moment of area, or I value)
Experiments to find the deflected 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.
Experiments to find the relationship between angular deflection and the dimensional and material properties of rods and tubes (torsional stiffness).

Specifications
Rigid metal frame with two adjustable knife-edges (ie “frictionless” pivots, hence beam is “simply supported”)
Max distance between knife edges = 400 mm
Back panel has a linear scale with 5 mm increments
Max loading on beam = 30 N
A dial indicator mounts magnetically on the back panel. It shows beam deflections up to 10mm at the point of loading in increments of 0.01 mm
Includes Vernier gauge
Fully adjustable feet
