Question

Explain how can we measure frictional Force

Answer 1

Answer:

An easy way to measure the coefficient of static friction is to place two objects together and then tilt them until the top one slides. The angle at which one object starts to slip on the other is directly related to the coefficient. When the two objects are horizontal there is no frictional force.

Explanation:

tribometer

In the 1700s, the term “tribometre” was coined by Goldsmith to refer to a device to measure friction, but in current usage, the scope of the term tribometer has been broadened to mean an instrument used to measure friction

Answer 2

Answer:

To measure the static coefficient of friction under conditions of high contact pressure the object may be clamped between two surfaces .The force necessary to put the object in motion must be halved to obtain the friction force because of the two contacting surfaces.
