A uniform 4m long ladder (ML = 50kg) is leaning against the wall at 65° above horizontal. There is no friction between the wall and the ladder but there is friction between the ladder and the floor. Determine the normal forces on each end of the ladder and the frictional force on the bottom of the ladder.

A uniform ladder 15 feet long is leaning against a frictionless wall at an angle of 53 degrees above the horizontal. The weight of the ladder is 30 pounds. A 75-pound boy climbs 6.0 feet up the ladder. What is the magnitude of the friction force exerted on the ladder by the floor? I have that the answer is 34. I'm just wondering why the x-components of the weights don't contribute to the net force in the x. many thanks....

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. Since the floor is rough, it exerts both a normal force n, and a frictional force r, on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L = 4.3 m, a weight of w. = 67.5 N, and rests against the wall a distance d...
