TM 441 THIN CYLINDER
GENERAL DESCRIPTION

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.

Instruction manual is also included.

TYPICAL EXPERIMENTS
  • 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.
