Causes and character of flexure variations of the Wanschaff vertical circle installed in the new pavillon.
Abstract
The present work describes a series of flexure determinations carried out on a Wanschaff vertical circle. It was concluded that transportation and installation did not lead to the flexure variations observed. Modifications of the tube increased its rigidity and stability.
