11 A solid steel shaft 30 cm in diameter is rotating at a speed of 300 r.p.m. If the shaft is constrained at its ends so that it cannot expand or contract longitudinally, calculate the total longitudi- nal thrust over a cross-section due to rotational stresses. The density of steel is 7800 kg/m³ and v= 0.30.

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
