Solids can be subjected to shear stresses, and to [[normal stress]]es—both [[Compressive stress|compressive]] and [[Tensile stress|tensile]]. In contrast, ideal fluids can only be subjected to normal, compressive stress which is called [[pressure]]. Real fluids display viscosity and so are capable of being subjected to low levels of shear stress. |
