What effect does friction have on a flexible system?

As the frictional force increases, while the flexible system's adaptability to the source of friction remains the same the effect of friction frictional on a flexible system approximates the effect of frictional force on a rigid system

Explanation:

A flexible system is one that adapts to a broad range of scenarios and possibilities depending on the degree of flexibility.

Therefore, the effect of friction on a flexible system is equivalent to the effect of a frictional force on a rigid body less the adaptability of the flexible body to the source of friction.

Therefore, as the frictional force increases, while the flexible system's adaptability to the source of friction remains the same the effect of friction frictional on a flexible system approximates the effect of frictional force on a rigid system

An example is the effect of frictional force on the internal surface of a pipe carrying incompressible flowing fluid. The speed of flow increases from 0 at the pipe wall to maximum at the center of the pipe cross section.
