verification of the solid friction
Answers
Explanation:
Friction Test Methods Using Weights and Pulleys. The friction coefficient can be calculated for simple geometries using arrangements of weights and pulleys. ... Pulling a block on a flat surface with a load sensor yields the friction force, F in the basic friction equation, F = μN, where N is the normal force.

Answer:
We study the influence of solid frictional forces acting on polymer chains moving in a random environment. We show that the total reduction in the chain tension resulting from the small friction between a polymer and fixed entanglement points is a steep nonlinear function of the number of entanglements (exponential for stretched chains). Therefore, solid friction can drastically change the dynamics and lead to trapping of long chains with a large number of entanglements.
