Calculating Tensile Stress |
The formula is
Tensile Stress = Force / Cross Sectional Area
Tensile Stress: Megapascals
(Mpa)
Force: Newtons (N)
Cross Sectional Area:
Square millimeters (mm^{2})
We have a 4,543.325 newton force acting on a 305 Stainless Steel (annealed) wire with a cross sectional area of 39.25 mm2.
Can the wire stand that force without breaking?
4,543.325 Newtons / 39.25 mm^{2} = 115.75 Megapascals
Because 305 Stainless Steel (annealed), wire as listed on www.matweb.com has a tensile yield stress of 325 Megapascals, the wire can hold the force in mid-air with a safety factor of 2.8.
325 Megapascals / 115.75 Megapascals = 2.8 Safety Factor
