Question

Define Co-efficient of static friction ​

Answer 1

Explanation:

The coefficient of static friction is the friction force between two objects when neither of the objects is moving. ... The coefficient of dynamic friction is the force between two objects when one object is moving, or if two objects are moving against one another.

Answer 2

Answer:

The Coefficient of Friction

Coefficient of friction can be defined as the ratio of the force of friction between two bodies and the force pressing them together [26]. Kumar et al. [27] studied the influence of particle size, reinforcement content, load and speed on the coefficient of friction at constant load and speed. They observed that the coefficient of friction decreased with an increase in FA content at a constant load and speed. The coefficient of friction of composite materials was greater than that of the aluminum alloy. The coefficient of friction also increased with an increase in FA particle size. The rise in the abrasive resistance by coarse particles most likely explained the increase in coefficient of friction and therefore decreased the wear volume. They observed for a constant FA particle size and percentage of FA, a rise in load and speed decreased the coefficient of friction. Rao and Das [19] investigated the influence of SiC content and sliding speed on wear performance of aluminum composites. They observed that the coefficient of friction increased with increasing of SiC content, but decreased with rising sliding speed. In summary, the coefficient of friction decreased with an increase in the percentage of FA, load, and speed and increased with an increase in particle size.
