Question
A ladder of length L = 2.4 m and mass m = 14 kg rests on a floor with coefficient of static friction μs = 0.55. Assume the wall is frictionless.
1) What is the minimum angle the ladder must make with the floor to not slip?
2) A person with mass M = 61 kg now stands at the very top of the ladder. What is the minimum angle to keep the ladder from sliding?

The other end rests against the wall, where it is held by friction as shown in the figure below. The coefficient of static friction between the wall and the rod is μ = 0.465. Determine the minimum distance x from point A at which an additional object, also with the same weight F, can be hung without causing the rod to slip at point A.
