PhysCasts: A Leaning Ladder
Rowlands, W. (Wayne) (2013)
This PhysCast is going to look at static equilibrium applied to a ladder leaning against a wall. A ladder of mass m and length L is leaning against a wall. The wall is frictionless and the coefficient of static friction between the ladder and the ground is mu. Find an expression for the minimum angle which the ladder can be lent without slipping?
