A uniform stationary ladder of length L = 5.5 m and mass M= 11 kg leans against a smooth vertical wall
A uniform stationary ladder of length L = 5.5 m and mass M= 11 kg leans against a smooth vertical wall, while its bottom legs rest on a rough horizontal floor. The coefficient of static friction between floor and ladder is μ=0.35. The ladder makes an angle θ=54° with respect to the floor. A painter of mass 8M stands on the ladder a distance d from its base.Part (a) Find the magnitude of the normal force N, in newtons, exerted...

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
N1
and a frictional force
f1
on the ladder. However, since the wall is frictionless, it
exerts only a normal force
N2
on the ladder. The ladder has a length of
L = 4.85 m,
a weight of
WL = 62.5 N,
and rests against the wall a distance

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...

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. N2 mg d N. Since the floor is rough, it exerts both a normal force N, and a frictional force f, 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 wall a distance d 3.75 m above the floor. If a person with a...

A 74 kg rock climber has positioned himself as shown in the figure (with his hands on one side of a gap and his feet on the other side). Both friction and normal forces act on his hands and feet. The width of the gap, w, is 0.28 m and the climber's center of mass is a horizontal distance d = 0.44 m from the gap. The coefficient of static friction Hi = 0.46 between his hands and the rock...
