Question #54771

What are the conditions for the mechanical equilibrium of a rigid body?

A ladder is placed against a wall making an angle θ with the floor. The wall is frictionless

but the coefficients of static and kinetic friction for the floor are µs and µk,

respectively.

Obtain an expression for the smallest value of θ for the ladder to not slip.
