| Question | Answer |
| tensile stress in the wire sigma=T/A unit of tensile stress is pascal(pa) Nm squared REMEMBER: is tension per unit cross-sectional area | tensile strain= E=diffirence in L/L where difference in L is the extension strain is a ratio so it has no units REMEMBER: strain is extension per unit of lenth |
| the value of stress to strain is a constant known as the young modulus | yound modulus= stress divided by strain =T over A divided change in L over L= TL over A difference in L |
