A 387-kg steel beam of length 5.00 m is attached to a wall by a hinge, and kept level by a cable attached to it at a 30.0◦ angle. The maximum tension that the cable can sustain before breaking is 13.0 kN. There is a support that allows a mass to be hung from the beam, three-quarters of the way along its length. (a) What is the maximum mass that can be hung from the beam before the cable snaps? (b) At this maximum mass, what is the magnitude and direction of the reaction force F from the wall against the hinge?

One end of a uniform ℓ = 4.70-m-long rod of weight w is supported by a cable at an angle of ? = 37° with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod is ?s = 0.520. Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A.

One end of a uniform ℓ = 4.40-m-long rod of weight w is supported by a cable at an angle of ? = 37° with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod is ?s = 0.570.  Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A._______________________ m

One end of a uniform € = 4.30-m-long rod of weight w is supported by a cable at an angle of 8 = 37° with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod is μ = 0.450. Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A. 9 R Q

a uniform beam of weight 500 N and length 3.0 m is suspended horizontally. On the left it is hinged to a wall; on the right it is supported by a cable bolted to the wall at distance D above the beam. The least tension that will snap the cable is 1200 N. (a) What value of D corresponds to that tension? (b) To prevent the cable from snapping, should D be increased or decreased from that value?

In a city park a nonuniform wooden beam 4.00 m long is suspended horizontally by a light steel cable at each end. The cable at the left-hand end makes an angle of 30.0° with the vertical and has tension 620 N. The cable at the right-hand end of the beam makes an angle of 50.0° with the vertical. As an employee of the Parks and Recreation Department, you are asked to find the weight of the beam and the location of its center of gravity.

One end of a uniform - 3.60-m-long rod of weight w is supported by a cable at an angle of 6-37° with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod is,-0.460. Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A

One end of a uniform 4.0-m-long rod of weight w is supported by a cable (at 37 degrees from the horizontal).   The other end rests against a wall, where it is held by friction. (see the figure.)   The coefficient of static friction between the wall and the rod is μs = 0.50. Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A.

One end of a 2.00 m uniform meter stick is placed against a vertical wall. The other end is held by a lightweight cord that makes an angle θ with the stick. The coefficient of static friction between the end of the meter stick and the wall is 0.530. When θ = 16.5°, how large must the coefficient of static friction be so that the block can be attached 0.800 [m] from the left end of the stick without causing it to slip?
