In the figure, a bar of length L is attached by a frictionless hinge to a wall and held horizontal by a rope that makes an angle with the bar. The bar is uniform and has weight W. A mass of weight Wis suspended a distance x from the hinge. If the tension T in the rope equals 2W, x must be equal to: (Hint: use torques) T L O OL(sin 0-1) OL OL(2sin - 2)

A 45.0 kg uniform rod 4.40 m long is attached to a wall with a hinge...
A 45.0 kg uniform rod 4.40 m long is attached to a wall with a hinge at one end. The rod is held in a horizontal position by a wire attached to its other end. The wire makes an angle of 30.0 ∘ with the horizontal, and is bolted to the wall directly above the hinge. If the wire can withstand a maximum tension of 1300 N before breaking, how far from the wall can a 70.0 kg person sit...
A uniform bar 7.5 m long is held against a rough wall by a light rope...
A uniform bar 7.5 m long is held against a rough wall by a light rope as shown in the diagram. The pulley may be assumed to be frictionless, W = 140 N and the weight of the bar is w = 40 N. Find (a) the tension in the rope attached to the bar, and (b) the minimum coefficient of friction between the bar and the wall if the bar does not slip. There is no hinge connecting the...

A 4.0- m-long iron bar of uniform cross section is held
perpendicular to the wall by a wire from the end of the bar to the
wall (see the figure). The bar is fastened to the wall with a
hinge. What is the tension in the wire if the iron bar weighs 700 N
and the wire is 5.0 m long?

A uniform bar of length 3.9 m and mass 4.2 kg is attached to a wall...
A uniform bar of length 3.9 m and mass 4.2 kg is attached to a wall through a hinge mechanism which allows it to rotate freely. The other end of the bar is supported by a rope of length 5.1 m which is also connected to the wall as shown above. What is the tension in the rope in N?
A 4-m long, 150-kg steel beam is attached to a wall with one end connected to a hinge that allows the beam to rotate up and down. The other end of the beam is held in a horizontal position with a cable that makes a 27° angle with the beam and is attached
A 4-m long, 150-kg steel beam is attached to a wall with one end connected to a hinge that allows the beam to rotate up and down. The other end of the beam is held in a horizontal position with a cable that makes a 27° angle with the beam and is attached to the wall (see (Figure 1)). What is the tension force that keeps this beam in static equilibrium?
A uniform beam of length 10.0 m and mass 50.0 kg is attached to a wall...
A uniform beam of length 10.0 m and mass 50.0 kg is attached to a wall at one end and free to pivot at this point. The beam is held horizontal by a cable attached to the far end of the beam and to a point on the wall 5.77 m above the pivot point. The angle between the beam and the cable is 30 degrees. A. What is the tension in the cable? B. What force is exerted by...
