Technical Description
The main component of this table unit is a thin-walled metal cylinder. It is sealed on one side with a piston which can be repositioned with a hand wheel. This makes it possible to create either the dual-axis stress state of a sealed container or the single-axis stress state of a tube. The cylinder is filled with oil and is hermetically sealed and maintenance-free. The internal pressure is generated with a hand-activated hydraulic pump and displayed on an easy-to-read manometer. Five measuring tapes are attached around the perimeter at angles of 0°, 30°, 45°, 60° and 90° to the cylinder axis to measure the elongation. The unit is used in conjunction with the measuring amplifier FL 151.
Learning Objectives / Experiments
· Determination of the principal stresses of an open cylinder (open tube)
· Determination of the principal stresses of a closed cylinder
· Comparison of open/closed cylinders
· Determination of transversal contraction coefficient
Features
· Direct stress can be measured on container along length and tangentially
· Closed container or open tube can be illustrated
