Steel wire with a stiffness of 1,000,000 N / m lengthened by 0.002m. With what force did you act on the wire?

To find the force with which they acted on the steel wire used, we apply Hooke’s law: F = Fcont = k * Δx.

Variables: k is the stiffness of the steel wire (k = 1,000,000 N / m); Δx – wire elongation (Δx = 0.002 m).

Calculation: F = k * Δx = 1,000,000 * 0.002 = 2 * 10 ^ 3 H = 2 kN.

Answer: The steel wire used was acted upon with a force of 2 kN.
