Mechanical property tells us about how the body will behave
under certain loading condition .... These properties depend on the
material of the body such as grain size, grain orientation etc.
Examples of Mechanical properties - Tensile Strength, Buckling
Strength, Ductility,Hardness etc.
Physical property tells us about the state of the body i.e.
whether it is solid or liquid or gas , what's is the surface
roughness , what is viscosity .... Roughly all the parameters that
tells us about the physical condition of a body are physical
property parameter
Ex- Viscosity, Roughness, Density etc.
