Problem 2 A uniform draw bridge of mass 1000 kg and length 8 m is partially drawn such that it makes an angle of 30° with the positive x-axis. It is maintained stationary by a rope attached 2 m away from the end of the bridge. The rope makes an angle of 40° with the bridge. This is summarized in the diagram below: 40° 2 m 30° pivot A) (4 points) Draw an extended force diagram for the draw bridge. Label the Wrces. You may have to guess one of the forces; for this particular force, you will not be penalized for an incorrect guess. B) (10 points) Find the magnitude of the force provided by the rope. C) (6 points) Find the magnitude of the pivot force. 9:30 AM 7/29/2020 Р Prt Scnfs Home F9 End PgUp FII F10 F6 F7 + & * ( 7 00 9 0 o P.
