Thin Cylinder Experiment

Internal pressure is applied to the cylinder by mean of a 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. Thin Cylinder Experiment is used for studying the stresses in a thin wall cylinder. The strain gauges are fixed onto 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 indicator. A thin wall aluminum alloy cylinder is mounted on a rigid steel frame. By applying the hand screw, only circumferential stress occurs on the cylinder or both circumferential and axial stresses occur.

Experiments:
Measurement of strains and stresses under internal pressures.
Comparison of theoretical stresses and strains with experimental values.
Determination of Youngâ„¢s modulus an Poissons ratio.
