## Homework Statement

Consider the rod as shown in the figure. The coefficient of static friction at A and B is \mu_s. I'm trying to find how big and how small the ratio l/d can be for the rod to still be in equilibrium. I have calculated how big all forces are acting upon the rod in the case just before sliding happens, but I'm not sure how to proceed.

## Homework Equations

Just before sliding happens the friction force F is F = \mu_s * F_n, where F_n is the normal force.
