Newtonian and non-Newtonian applies to liquids not fluids.
Liquid is a fluid but fluid is not necessarily a liquid.
Fluids are liquid, vapour, gas and plasma.
Water is a Newtonian liquid; the viscosity is constant, at
constant temperature irrespective of shear.
Ketchup is a non-Newtonian liquid; the viscosity varies
depending upon the shear and the length of time the shear
which one of the following loading is considered for the
design of axle.
1)bending moment only 2) twisting moment only 3) combined
bending moment & torsion 4) combined action of bending
moment & axial thrust
