What is the coefficient of friction if the normal force is 80 N and the friction force is 32 N?

To determine the coefficient of friction, the formula to use is:

[

\text{Coefficient of Friction} (\mu) = \frac{\text{Friction Force}}{\text{Normal Force}}

]

In this scenario, the friction force is given as 32 N, and the normal force is 80 N. Plugging in these values:

[

\mu = \frac{32 , \text{N}}{80 , \text{N}} = 0.4

]

Thus, the coefficient of friction is 0.4. This value indicates how much frictional force is generated per unit of normal force, reflecting the interaction between the surfaces in contact. It is a dimensionless quantity, helpful in understanding the efficiency of frictional force in various applications. The answer aligns accurately with the calculations, confirming its correctness and relevance in real-world applications like determining safe slopes for ramps, vehicle traction, or any systems involving movable parts.
