The apparatus demonstrates the use of electrical resistance strain gauge in measuring strain of material under stress. It is to be used with ST305 Universal Base Frame.
A beam is simply supported at both ends. Strain gauge(s) are fixed at different locations of the beam specimen. Each gauge is wired to form a full bridge with temperature compensation and zero adjustment. Load is applied by a load hanger and weights. Strain(s) are measured by a strain indicator.
