Static problem with three cylinders

Static problem

 

Three identical cylinders of mass m are arranged in a triangle as shown:

 

 

The friction coefficient between cylinders is "u1" and between cylinders and ground "u2". What condition must satisfy "u1" and "u2" to remain the system in equilibrium ?

 

Thanks in advance!

Ok I solved it, the solutions are:

 

Friction coefficient between cylinders: 0.268

Friction coefficient between cylinders and ground: 0.089

Now, think about this condition, as a brain teaser: What if the cylinders were toothed gears instead of cylinders? imp
