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.

The equipment is used for studying a stress profile in the wall of a thick cylinder.

Two halves of thick aluminum alloy cylinders are cemented and clamped together. A hand operated hydraulic pump transmits pressure to the inside of the cylinders via the clamping bolt. The pressure is indicated by a pressure gauge.

Strain gauges are of the same gauge factor and the gauges are attached radially and circumferentially along the wall thickness and filled with jointing material. Additional strain gauges are attached on the inside and outside surfaces of the cylinder.  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.

  • Measurement of strains, hence stresses, along the cylinder wall thickness.

  • Comparison of the actual strain readings with theoretical values.

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.

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.

Instruction manual is also included.

  • Measurement of strains and stresses under internal pressures.

  • Determination of Young’s modulus a Poisson’s ratio.

  • Comparison of theoretical stresses and strains with experimental values.
