Strain and Stress in a Beam
Strain and Stress in a Beam — demonstrates how electrical resistance strain gauges measure material strain under stress. For use with ST300 or ST305 Frame.
Description
Strain and Stress in a Beam. The apparatus demonstrates the use of electrical resistance strain gauge in measuring strain of material under stress. It is to be used with ST300 Universal Structural Frame or ST305 Universal Base Frame (separately supplied).
A beam is simply supported at both ends. Strain gauge(s) are fixed at different locations of the beam specimen. Each gauge is wired to form a full bridge with temperature compensation and zero adjustment. Load is applied by a load hanger and weights. Strain(s) are measured by a strain indicator.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Examination of the relationship between stress and strain
- Finding the neutral axis
- The effect of beam cross-section to the second moment of area and neutral axis
