Electric strain gage

In cooperation with Engineering Foundation, the design of a carbon resistor cartridge for measuring deformation in mass concrete has been undertaken with particular reference to the study of arch dams. A particular reference to the study of arch dams. A cartridge made up which is now being given a series of laboratory trials to determine temperature and other effects. It is planned to make up a number of these cartridges and embed them in concrete with a view of determining the effects of shrinkage and other factors as an aid to interpreting results obtained in field work.
