Sc1 Investigation - bending of a Cantilever. Experiment to measure deflection when a force is applied to a cantilever. Introductory Diagram Aim To find out whether varying the load has any affect on the deflection (?d) of the ruler. Theory Elasticity is the property, which allows a material to regain its shape after being distorted. Some materials like, rubber bands, are much more elastic than others. The elastic limit of a material is the maximum amount by which it can be stretched and still regain its original shape after the distorting forces are removed. If a material is stretched beyond its elastic limit its shape is permanently changed. ' The deformation of a material is proportional to the force is applied to it, provided the elastic limit is not exceeded'. This is known as Hooke's Law, named after its discoverer, Robert Hooke, a 17th century scientist. Young's Modulus When stress is applied to a material, strain is produced...
