Question

Elasticity in materials LAB

1. For the second run, do you notice nonlinear behavior at high tension force? Does this indicate the material is becoming stiffer or slinkier?

2. For a wire that has twice the radius of our wire, how much would it stretch in comparison to our wire if the other expirmental condition were the same? The same? Twice? Half? Four times as much?

Answer 1

1. Nonlinearity indicates it is slink.

For high tension force object looses it's elasticity.

2. If radius of the wire is twice, if all other cinditcond are same then it elongates one fourth of out wire.elong is inversely proportional to square of radius of wire.
