A woman whose weight is 418 N is poised at the right end of a diving board with a length of 8.95 m. The board has negligible weight and is bolted down at the left end while being supported 2.55 m away by a fulcrum. Find force that the fulcrum exerts in the board. Note: Express your answer in whole numbers.

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 wrecking ball (weight = 5670 N) is supported by a boom, which may be assumed to be uniform and has a weight of 2760 N. As the drawing shows, a support cable runs from the top of the boom to the tractor. The angle between the support cable and the horizontal is 32°, and the angle between the boom and the horizontal is 48°. Find (a) the tension in the support cable and (b) the magnitude of the force exerted on the lower end of the boom by the hinge at point P. (a) Number (b) Number Mk Support, cable Units Units N N 48 Boom

A uniform bar with a length of 6.88 meters and a mass of 29 kg is attached to a building by an axis at its left end. A box of mass 38.4 kg sits on the bar at a distance of 2.4 m from the left end. The right end of the bar is supported by a cable with a 477.81 N of tension that is also attached to the building. The angle between the cable and the bar is 34.9°. Determine the Fv, the vertical force on the bar by the wall (in N).
