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. Pressure in the diaphragm is indicated on a pressure gauge. A dial gauge is fitted onto a cross bar to measure the diaphragm surface profile. Scale on the cross bar indicates the dial gauge position.

Strain gauges are of the same gauge factor and the gauges are fitted onto the diaphragm at different angles and radii. 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.

Instruction manual is also included.

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 screw is attached on a frame to open or close one side of 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.
