Homework Statement
Homogeneous cube with one edge lying on the floor and the other on a smooth vertical wall. The underside of cube with a horizontal surface makes angle of [tex]\frac{\pi}{6}[/tex].What is the value to the coefficient of friction between the cube and the floor to cube remain in balance.
Homework Equations
[tex]\sum F=0[/tex]
[tex]\sum M=0[/tex]
[tex]M=rF[/tex]
M is momentum of force.
The Attempt at a Solution
In static case
[tex]\sum F=0[/tex]
[tex]\sum M=0[/tex]
I need help to write this equation from the problem statement. I don't have idea.
Because cube is homogenuous the forces are equal from all parts I suppose.
My assymption is that [tex]r[/tex] is size of cube so [tex]a[/tex]. Do you have any idea? I think this goes in one line but it is hard for me.
