Title1R20.15-2 - Young's Modulus - Stretching of a Copper wire - Vertically
Objective

​To demonstrate how much a copper wire will stretch when a force is applied as it is related to the Young's modulus.

StatusAvailable
Assembly Instructions

​To tie a loop in the 30 gauge copper wire, use a Blood Knot.  (wrap each end around wire 4 times in opposite directions, then feed end through in opposite directions and tighten.  Don't pull too hard or you will break the wire).  Begin by hanging 20g mass from wire to keep it taught.  Alighn arrow with bottom of loop of wire.  then when ready to run demo, add mass and watch wire stretch.  Will break typically above 2.25kg.

Operation Instructions

Start by ​hanging the 20g mass from the wire and position the arrow at the bottom of the loop.  Remove the 20g mass and hang a heavier mass on to see the wire stretch.  The wire usually breaks at 2.25kg or above.  Typically we add a 1kg mass, then another 1kg mass, then finally either a 250g or 500g mass to put the total mass past the wire's breaking point.
