Spring steel specimen struts are supported between two chucks; one in the top of the apparatus and one within the screwjack loading mechanism. The chucks have a integral precision slot into which the test strut ends can fit. alternatively a knife-edge block can be fitted into the chucks which mate with equi-spaced 'V' grooves in the end face of the specimen ends. This variety ensure that pinned/pinned, fixed/pinned or fixed/fixed end conditions are created.
The struts are compressed using the loading mechanism supplied. As the strut starts to deform, the amount of deflection is recorded using a dial gauge. The dial gauge can be moved up and down the strut length so that the deflection can be seen at various points.
Both the load cell output and dial gauge output must be fed directly into the HDA200 Interface (sold separately).
