Experimental setup

The shaft I is of the form shown in schematic Fig. 3 and is located in chuck F and phosphor bronze retainer N. The diameter of the shaft used in this experiment is 3.310 mm (approx.) and the length, l, of the specimen is 0.9144 m. The material is AISI 4130 steel with E = 200 GPa and ρ = 7850 kg/m³.

The support chucks F and N have been so designed as to allow the shaft movement in a longitudinal direction, for the purpose of location before tightening, and also provide directional clamping of the shaft end. With the standard apparatus, chuck N provides directional fixing to the end of the shaft, although an interchangeable sliding chuck T is available which provides a directionally free support.

A movable support E is provided with chuck F which, when moved to the right from the position shown in the diagram, provides the motor end support with directional freedom identical to that of chuck T. Thus, by selection of the required supports, any combination of fixed or free end conditions may be selected.
