<p>An extensometer support and counterbalance system (33, 38, 44, 46, 53, 55, 60) having vibration damping mountings (43A, 43B, 98, 156) for parts that have substantial mass and which are subjected to external vibrations. Such parts include counterweights (155A, 155B, 97A, 97B) for counterbalancing the extensometer and also the mounting (44, 46) for an external support frame (60) for the extensometer (53). The vibration damping comprises mountings made of a suitable damping material (43A, 43B, 98, 156), such as a silicone foam rubber (98).</p> |
