Magnitude and Units of Stress Magnitude of stress Stress=Force/Area, limit Area approaching zero Units of stress I Newton/m2 or a ' Pascal'l, or simply say"Pa That is 1 pascal= 1 newton per square meter newton=1 kilogram meter per second squared(1 kg m- a more commonly used unit is the bar or the kilobar, Where 1 bar=10 pascals=0. 1 MPaMagnitude of stress Stress = Force / Area, limit Area approaching zero Units of stress [ Newton / m2 or a ‘Pascal’], or simply say ‘Pa’ That is 1 pascal = 1 newton per square meter. 1 newton = 1 kilogram meter per second squared (1 kg m s-2 ) A more commonly used unit is the bar or the kilobar, Where: 1 bar = 105 pascals = 0.1 MPa Magnitude and Units of Stress
