- A uniform beam with a mass of 125 kg and a length of 6.00 meters rests on a fulcrum, which is directly under the left end of the beam. A vertically hanging rope is tied to the the beam, 1.50 meters from the right end. The beam is completely horizontal an is in a state of static equilibrium. 1.50 m (a) On the diagram above, label all of the external forces acting on the beam, using arrows. (b) What is the tension in the rope, in units of Newtons? (c) What is the normal force that the fulcrum exerts on the beam, in Newtons?A 1140-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end.

A uniform beam, length = 12 m, wt = 800 N, is hinged at the wall and makes an angle of 30° to the horizontal. A wire connected to the beam 2 meters from its end makes an angle of 45° to the beam. a) What is the tension in the wire? b) What is the vertical component of the force of the hinge and c) What is the horizontal component of the force of the hinge? 45 30
- A horizontal plank 4.00 m long and having mass 20.0 kg rests on two pivots, one at the left end and a second 1.00 m from the right end. Find the magnitude of the force exerted on the plank by the second pivot.A uniform 8.00 m, 1500 kg beam is hinged to a wall and supported by a thin cable attached 2.00 m from the free end of the beam. The beam is fixed to the wall at an angle of 30 degrees above the horizontal. The angle between the cable and the beam is 40 degrees. What are the unknowns? -direction of tension in the cable -direction of the hinge force -magnitude of rhe tension in the cable -magnitude of the hinge forceA uniform drawbridge must be held at a 38o angle above the horizontal to allow ships to pass underneath. The drawbridge weights 55000 N and is 15.0 m long. A cable is connected 3.5 m from the hinge where the bridge pivots (measured along the bridge) and pulls horizontally on the bridge to hold it in place. What is the tension in the cable? Find the magnitude and direction of the force the hinge exerts on the bridge. If the cable suddenly breaks, what is the magnitude of the angular acceleration of the drawbridge just after the cable breaks? What is the angular speed of the drawbridge as it becomes horizontal? What is the velocity of the drawbridge, just before it “hits” (i.e. goes horizontal)?
