a steel beam 5.0 m long with a mass of 80 kg is hinged at its left end to the wall. a heavy sign with a mass of 220 kg hangs from the beam 4.25m from the wall. the cable supporting the beam snaps, and the beam begins to fall. what is the initial angular acceleration of the beam?
1. A 2.0 m long rod is hinged at one end and connected to a wall (at the hinged end). It is held at an angle of 30° from the horizontal axis by a cable attached to the rod and to the wall, as shown in Fig. 1. Suddenly, the cable snaps (so the cable is no longer applying any tension force to the rod). The moment of inertia for various objects can be found on the back of the...
please explain what equation you use to solve this problem

A uniform beam of length 20.0 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 midpoint 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 20 .0 kg mass hangs from a second cable which is attached to the...
A 202 kg uniform, beam is hinged at one end and at the other is supported by a cable that is at 23 degrees to the left of the vertical. The beam is 2.8 m long and is at 6 degrees above the horizontal. Calculate the tension in the cable (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 to the wall. A mass of 75 kg is hung from the beam 3 meters away from the hinge (see (Figure 2)). Now what is the tension force...

A 3.0 m long horizontal pole (negligible weight), hinged at a wall, supports a 1500 N sign. The sign hangs 2.0 m from the hinge and, at the pole's other end, a cable pulls up and back at 53.1 degrees to the pole. (a) What is the Tension in the cable? (b) What is the horizontal part of the reaction force of the hinge on the pole?
In Fig. 12-33, one end of a uniform beam of mass 40.0 kg is hinged to a wall: the other end is supported by a wire that makes angles theta = 30.0degree with both wall and beam. Find the tension in the wire and the magnitude and angle from the horizontal of the force of the hinge on the beam.
A 207.8 kg uniform, a horizontal beam is hinged at one end and at the other is supported by a cable that is at 26 degrees to the left of the vertical. The beam is 2.63 m long. Calculate the direction of the force at the hinge (measured with respect to the horizontal). Answer with a number in degrees
A 206.8 kg uniform, horizontal beam is hinged at one end and at the other is supported by a cable that is at 29 degrees to the left of the vertical. The beam is 2.39 m long. Calculate the direction of the force at the hinge (measured with respect to the horizontal). Answer with a number in degrees
