Description
This apparatus is used for studying the stresses and strain in a thin wall cylinder. A thin-walled aluminium alloy cylinder mounted on a rigid steel frame. Internal pressure is applied to the cylinder by means of hydraulic hand pump. Pressure in the cylinder is indicated on a pressure gauge. A hand screw is attached to one end of the frame to operate a piston on one side of the cylinder. The piston can open or close the cylinder by applying the hand screw. When the cylinder is open, only circumferential stress occurs on the cylinder. When the cylinder is closed, both circumferential and axial stresses occur.
Strain gauges are of the same gauge factor and the gauges are fixed to the cylinder at different angles. Each strain gauge is wired to form a full bridge with temperature compensation gauge and zero adjustment in a bridge box with strain gauge multi digital display.
