What is the formula for tensile stress?

 Tensile stress is the force applied to a material per unit area when it is pulled or stretched. It is commonly denoted by the symbol "σ" (sigma). The formula for tensile stress is:

Tensile Stress (σ) = Force (F) / Cross-sectional Area (A)


  • Tensile Stress (σ) is the stress applied to the material in Pascals (Pa) or Newtons per square meter (N/m²).
  • Force (F) is the applied force in Newtons (N).
  • Cross-sectional Area (A) is the area perpendicular to the direction of the force in square meters (m²).

It's important to note that tensile stress is a measure of force per unit area and is a positive value when the material is under tension (being stretched). If the material is under compression (being squeezed), the stress is referred to as compressive stress and is typically denoted with a negative sign to indicate the direction of the force.
