1. The problem statement, all variables and given/known data The walls are smooth, calculate the reactions. the cylinder weighs 100[N]. Now the 600 wall is rough with a friction coefficient 0.4. what are the reactions 2. Relevant equations Friction: F=μN 3. The attempt at a solution I made the first step and it was good: N1=287.9, N2=253.2 But with friction there is another force, tangential, but the results in the book are the same.
