Question

Sierra asks Fumiko which has a greater Young's modulus, a steel wire or a rubber band, and why. Which response is correct?

Answer 1

1-"Because the rubber band is expected to stretch more for a given applied force, Young's modulus would be larger for the rubber band, so the rubber band would have the greater Young's modulus."
2-"Because the steel wire is expected to stretch more for a given applied force, Young's modulus would be smaller for the steel wire, so the rubber band would have the greater Young's modulus."
3-"Because the rubber band is expected to stretch more for a given applied force, Young's modulus would be smaller for the rubber band, so the steel wire would have the greater Young's modulus.
4-"Because the steel wire is expected to stretch more for a given applied force, Young's modulus would be larger for the steel wire, so the steel wire would have the greater Young's modulus."

Answer 2

well, first off, which one do you think is stiffer, a rubber band or a steel wire?

Answer 3

steel

Answer 4

good, so steel has the higher modulus

Answer 5

that is it ? the stiffer the material the higher young's modulus?
