Tension Coefficient Apparatus Model MT 077

Tension Coefficient Apparatus Model MT 077

Sci-tech Tension Coefficient Apparatus Model MT 077 consists of a jib restrained by two chain ties making a triangulated three-dimensional structure. The jib and both ties are fitted with spring balances so that the internal forces can be measured. The bottom of the jib is pivoted to the wall mounted plate and the tie attachment locations can be varied independently at their wall ends. A load is hung from the jib end, and the geometry returned to its unloaded state using a knurled collar before taking the spring balance readings

Size: 55cm x 55cm x 60cm (LxWxH)
Weight: 45 kg

Item Description

Sci-tech Tension Coefficient Apparatus Model MT 077 consists of a jib restrained by two chain ties making a triangulated three-dimensional structure. The jib and both ties are fitted with spring balances so that the internal forces can be measured.

The bottom of the jib is pivoted to the wall mounted plate and the tie attachment locations can be varied independently at their wall ends.

A load is hung from the jib end, and the geometry returned to its unloaded state using a knurled collar before taking the spring balance readings

Technical Specifications

Specifications
