A 200 N ladder that is 9.0 m long leans against a frictionless wall.  There is friction between the ladder and the floor.  A rope is attached to the ladder at a point 3 m above the bottom of the ladder (one third of the way up the ladder).  It is pulled horizontally to the left with a tension of 25 N.   If the coefficient of friction between the floor and the ladder is .67, what is the smallest angle the wall can make with the floor before it begins to slide down the wall.

A ladder leans against a wall 5 meters above the ground so a homeowner can clear his gutters of leaves from last fall.  The bottom of the ladder just begins to slip when it is 1.7 meters from the wall.  What is the coefficient of static friction between the bottom of the ladder and the ground?

One end of a uniform 4.30-m-long rod of weight F is supported by a cable at an angle of = 37° with the rod. 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 = 0.460. Determine the minimum distance x from point A at which an additional object, also with the same weight For can be hung without causing the rod to slip at point A. m 0 B ✪

A scaffold of mass 79 kg and length 5.0 m is supported in a horizontal position by a vertical cable at each end. A window washer of mass 84 kg stands at a point 1.1 m from one end. What is the tension in (a) the nearer (relative to the person) cable and (b) the farther (relative to the person) cable? (a) Number i Units (b) Number i Units

A 10 m long board has a mass of 7 kg. The left end of the board is against a wall and it sticks straight out like a boom.  A rope is tied 1 m from the right end of the board and makes a 44 degree angle with the boom. A 25 kg box hangs 3 m from the right end. Find the tension in the rope.

Please help: A 12.8 m ladder whose weight is 200 N is placed against a smooth vertical wall. A person whose weight is 500 N stands on the ladder a distance 2.2 m up the ladder. The ladder makes an angle of 31 degrees with the vertical wall (see figure) Find the normal force exerted by the floor on the ladder.

A fence post of mass m = 8 kg supports a fence with three lengths of barbed wire. The bottom wire is a distance d = 0.35 m from the ground and each wire is a distance 0.35 m above the previous one. Each of these three wires has the tension on it. For this problem, assume that the force exerted by these wires is purely horizontal. An additional guy wire is used to keep the pole upright with a tension of Fa = 490 N. The guy wire attaches to the post at a point h = 0.86 m above the ground and makes an angle of θ = 45 with respect to the horizontal. Write an expression for the tension in any one of the three fence wires.  What is the normal force that the ground exerts upward on the post?

A 2.99 m long ladder that has a mass of 5.84 kg leans against a frictionless wall. The coefficient of static friction between the ladder and the floor is 0.589. What is the maximum angle that the ladder can make with the floor without slipping if a 87.6 kg person stands half-way up the ladder? θ =  °
