If an object is placed against an object, then the frictional force will be the same as the weight of the object. If an object is pushed against the surface, then the frictional force will be increased and become extra than the weight of the object. The full amount of friction force tha...
A frictional force is an important property associated with the motion of the substances and cannot be eliminated, however the frictional forces acting on the body may be mitigated with the use of lubricating fluids or gels that can make the surface slippery. In general, a frictional force exist...

DEFINITION Friction is the resistance to motion when two bodies in contact slide on one another. The frictional force F is the force required to initiate or maintain motion. If W is the normal reaction of one body on the other, the coefficient of frictionμ is defined as μ = F/W. STAT...
Thus, the frictional forceqSis replaced by its twin effects: (i) as a tension on the pipe and (ii) as a pressure drop in the fluid.Equation (3.66), when integrated fromxtoLgives(T−pA)x=(T−pA)L, the equivalent ofequation (3.36). Ignoring externally imposed tensioning and pressuriz...
When a liquid whose viscosity decreases as its temperature increases is made to undergo a simple shearing flow the wall speed, or the centreline temperature, is a double valued function of the wall stress. This is called the base solution curve and the turning point is called the nose of th...
