Answer 2

Calculation of Force Required to Stretch a Wire

To calculate the force required to stretch a wire, we can use Hooke's Law, which states that the force required to stretch or compress a spring-like object is directly proportional to the displacement produced. The formula for Hooke's Law is:

F = k * ΔL

Where: - F is the force applied to the wire, - k is the stiffness or spring constant of the wire, and - ΔL is the change in length of the wire.

In this case, we are given that the stiffness of the wire is 2000 N/m and we want to stretch the wire by 1 mm (0.001 m). Therefore, we can substitute these values into the formula to calculate the force required:

F = 2000 N/m * 0.001 m

Calculating this, we find that the force required to stretch the wire by 1 mm is:

F = 2 N

Therefore, a force of 2 Newtons is required to stretch the wire by 1 mm.
