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.

Example E6 Pg 72 A vehicle of mass 3000 kg is being driven round a banked bend of radius 75 m on an icy day, calculate the maximum speed the vehicle can maintain without slipping outwards if the coefficient of friction between the road and the tyres is 0.2 and banking angle is 15°. Resolve force in the vertical and horizontal directions because the centripetal force is horizontal towards the axis of curvature. Note that N contributes to the vehicle's equilibrium in the vertical direction as well as maintaining the circular motion UN mg 15°

A 2:1 speed reduction drive (Fig Q4) between two parallel shafts at 1200 mm centre distance is being provided by a V-belt of mass 0.5 kg/m. The diameter of the driving pulley is 200 mm and the driving shaft rotates at 900 rev/min. The driven pulley is 400 mm diameter. The angle of the pulley grooves is 40°, and the coefficient of friction between belt and pulleys is 0.35. If the maximum beit tension is 400 N determine: (i) The linear belt speed and the centripetal tension due to that belt speed.
