The Young modulus $E$ may be found using measurements taken while a wire is under tension. Which quantities need to be measured in order to determine $E$?
- Amass of stretching load; original length of wire; diameter of wire; extension of wire
- Bmass of stretching load; new length of wire; cross-sectional area of wire; diameter of wire
- Cmass of wire; original length of wire; cross-sectional area of wire; new length of wire
- Dmass of wire; new length of wire; diameter of wire; extension of wire
