Lab 7:ElasticityDavid LiuMarch 25, 2015Individual ReportPhysics 2AGroup 3Group Members:Mohammad HussainJuliet SanchezDaniel BelmarPURPOSE:
The main purpose of this experiment is to study the elasticity of some of the solid materials by using a method called Young’s Modulus. Since elasticity is an important property of a solid material, as when force is acting upon an object, the displacement of the object conserves just as much force as it is applied on, and this experiment will help us define the method to calculate the elasticity of solid objects.EQUIPMENT:1.Metal stand.2.Helium-Neon laser3.Tripod with reflector4.Thin wire made of steel/aluminum5.Weights in increments of 100g6.Whiteboard (for the laser to be reflected upon)7.Measuring toola.Meter stickb.Vernier caliperPROCEDURE:Set up the metal stand (with the top of the metal stand as A) with the wire hanging downwith a weight attached to the end of the wire. The initial weight (with the weight attachedto the wire) will be accounted as zero since it is the initial trial. On the platform which should be adjusted to similar height of the table students are to be working on (this location will be accounted as B), is where the reflector is to be placed, and on the opposite end of the table, set up the whiteboard so the laser can be reflected upon it.
