A 300-N uniform plank leans against a frictionless wall as shown. The length of the plank is L, and the exact length is not needed to be known to solve this problem. There is friction between the floor and the ladder. Find the minimum coefficient of static friction between the ladder and the floor needed to prevent the ladder from slipping.

A uniform ladder of mass mL = 12.3 kg and length L = 3.80 m is leaned against a frictionless wall at an angle of θ = 23.4∘, as shown in Figure 2. A human, of mass mh = 83.8 kg, stands a distance d = 1.10 m up the ladder as shown. What is the minimum coefficient of static friction between the ladder and the ground that will prevent the ladder from slipping?

In the figure, a uniform plank, with a length L of 4.75 m and a weight of 630 N, rests on the ground and against a frictionless roller at the top of a wall of height h = 2.36 m. The plank remains in equilibrium for any value of θ = 70.0∘ or more, but slips if θ < 70.0∘. Find the coefficient of static friction between the plank and the ground.

A ladder (length L, and uniformly distributed mass, mL), is leaning against a wall at an angle of θ (see figure below). A man (mass mM ) is standing on a rung of the ladder that is a distance of L/3 from the floor measured along the ladder. The vertical wall is frictionless, and the horizontal floor has a non-zero coefficient of friction, μ. a) (3 Points) Draw a free body diagram indicating all forces acting on the ladder as vectors, and label each one. b) (3 Points) Determine the Normal forces (one provided by the floor, and the other provided by the wall) as functions of the available constants (θ, mM, mL, L, μ, and the acceleration due to gravity, g). c) (4 points) What value of μ is needed to keep the ladder from slipping?
