Transducers for 18/11/05

Using strain gauges we will measure the Modulus of Elasticity of the Aluminium beam.
Do you understand how the equipment works?
How does Hooke`s Law help?
Remember Poisson`s ratio? How is it relevant to this experiment?

Record all your readings, perform the calculations and draw the Stress-Strain graph.
Comment on the accuracy of your findings.
