whats the difference between young's modulus,stress and
pressure.they have same unit

Answer Posted / kalyan kolavennu

yes, all of 3 have same unit (N/mm2)

1) Young's modulus is the property of material which is the
ratio of stress to strain within proportional limit.
E = stress/strain (N/mm2)

2) stress is the property of material which is the force of
resistance per unit area offered by a body against deformation.
Stress = Load/Area (N/mm2)

3) Pressure is the force per unit area.
Pressure = Force/Area (N/mm2)
