3. Physical properties
A physical property is a relationship between two measured
quantities.
The elastic compliance coefficients relate mechanical strain, the
dependent variable, to mechanical stress, the independent variable.
for small stresses and strains the relationship is linear.
Tensors are so useful in describing anisotropy.

4. Thermal conductivity , here the dependent variable
is heat flow and the independent variable is
temperatura gradient.
Hysteretic, in this case
magnetization is the
dependent variable
responsive to and
applied magnetic field
Under small fields
Ohms law governs the
relationship between
current density and
electric field
