## Homework Statement

The cylinder in the drawing weighs 100[N]. there is a horizontal rope at the top that prevents it from rolling. what is the coefficient of friction if it's on the verge of movement

## Homework Equations

Friction force: f=μN

## The Attempt at a Solution

The whole weight of the cylinder lies on the contact point. the coefficient of friction is the tangent of the slope, which is here 25

^{0}, thus μ=tan 25

^{0}=0.422

It should be 0.22
