A 210-kg load is hung on a wire of length of 3.20 m, cross-sectional area 2.000 10-5 m2, and young's modulus 8.00 1010 n/m2. what is its increase in length?

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
