Strength and Property of MaterialsCircular Diaphragm
The equipment is used for studying the stress and deflection of a thin diaphragm.
The circular aluminum alloy diaphragm is clamped around its edge by two heavy steel flanges. Internal pressure is applied to the diaphragm by a hydraulic hand pump.

Strength and Property of MaterialsThin Cylinder
This equipment is used for studying the stresses in a thin wall cylinder.
A thin wall aluminum alloy cylinder is mounted on a rigid steel frame. Internal pressure is applied to the cylinder by means of a hydraulic hand pump with oil reservoir. Pressure in the cylinder is indicated on a pressure gauge. A hand wheel is attached to one end of the frame to operate a piston on one side of the cylinder. By applying the hand wheel, the piston can open or close the cylinder. 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 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.
