Experiment Procedure
• Measure the deformation profile with loads in the centre and loads away from the centre.
• Measure the deformation as a function of the force.
• Measure the deformation as a function of the length, width and breadth as well as how it depends on the material and determine the modulus of elasticity of the materials.

Summary
A flat, level beam’s resistance to deformation in the form of bending by an external force can be calculated mathematically if the degree of deformation is much smaller than the length of the beam. The deformation is proportional to the modulus of elasticity E of the material from which the beam is made. In this experiment, the deformation due to a known force is measured and the results are used to determine the modulus of elasticity for both steel and aluminium.
