A ladder is leaning against a frictionless wall as shown in the picture to the right. The coefficient of friction between the ladder and the floor is 0.34. The mass of the ladder is 20 kg. There is a person walking up the ladder. The mass of the person is 60 kg. d = ?? m b = 4 m a = 7 m e. What is the maximum distance d that the person can walk up the ladder without...
A uniform ladder of length L and weight w is leaning against a vertical wall. The coefficient of static friction between the ladder and the floor is the same as that between the ladder and the wall. If this coefficient of static friction is μs = 0.585, determine the smallest angle the ladder can make with the floor without slipping.

2. A uniform ladder of mass m and length L stands on a floor at angle α, leaning against a frictionless wall.The static coefficient of friction between the ladder and the floor is μs. Calculate the minimum value of the angle α for which the ladder remains in equilibrium. Answer, I tan α > 2,, 2us
A ladder is leaning against a vertical wall, and both ends of the ladder are at the point of slipping. The coefficient of friction between the ladder and the horizontal surface is μ1 = 0.275 and the coefficient of friction between the ladder and the wall is μ2 = 0.153. Determine the maximum angle with the vertical the ladder can make without falling on the ground.
