To calculate for the length at which the length of the wire extended can be calculated through the equation,
extension = ((force)(length)) / ((Young's modulus)(area))
To calculate for the force one needs to find the weight of the object.
F = (210 kg)(9.8 m/s²)
F = 2058 N
Substituting the known values,
extension = ((2058 N)(3.2 m) / (8 x 10¹⁰ N/m²)(2 x 10⁻⁵ m²))
extension = 4.116 x 10⁻³ m
Answer: 4.116 x 10⁻³ m
