Question

Angle of friction between two surface is 30°. what is coefficient of friction between them​

Answer 1

Answer:

hope it helps u

Explanation:

The force straight down, due to gravity, on a mass m on the inclined plane is F = mg

The force parallel to the plane is Fp = mgSinθ and the force normal to the plane Fn = mgCosθ

The coefficient of friction is defined as μ = Fp/Fn

So μ =mgSinθ/mgCosθ = Tanθ

In this case, θ = 30°, so Tanθ = 0.577

The coefficient of friction is 0.577

Answer 2

As angle of friction here is 30 degree, coefficient of friction here = tan (30), which is 1/√3.

Explanation:

 

tan(angle of friction)= coefficient of static friction.
