The stress on the wire is determined as  6.37 x 10⁶ N/m².

Stress on the wire

The stress on the wire is calculated as follows;

σ = F/A

where;

  • F is the force applied on the wire
  • A is area of the wire

Let the diameter of the wire = 2 mm

Area = πr²

Area = π(1 x 10⁻³)²

Area = 3.142 x 10⁻⁶ m²

Stress = 20/(3.142 x 10⁻⁶)

Stress = 6.37 x 10⁶ N/m²
