Question

During running, the dynamic coefficient of friction (μ) can be calculated using which forμla, considering Fy as the anterior/posterior and Fz as the vertical force components?

a)μ=Fy/Fz
b)μ=Fx/Fz
​c)μ=Fz/Fy
​d)μ=Fz/Fx

Answer 1

The dynamic coefficient of friction (μ) can be calculated using the formula μ = Fy/Fz, considering Fy as the anterior/posterior and Fz as the vertical force components. So, the correct option is A.

Step-by-step explanation:

The dynamic coefficient of friction (μ) can be calculated using the formula μ = Fy/Fz, considering Fy as the anterior/posterior and Fz as the vertical force components.

For example, if you have a force Fy of 10 N and a force Fz of 20 N, the coefficient of friction would be μ = 10 N/20 N = 0.5.

Therefore, the correct formula to calculate the dynamic coefficient of friction is a) μ = Fy/Fz.
