A horizontal beam is balanced on a point pivot at x pivot = 0 . 200 m. The beam is uniform with mass 0 . 1 kg and the center of mass is at x beam cm = 0 . 500 m. There is also a single object of mass 2 kg on the beam. Where is it? 013 qfull 00200 2 3 0 moderate math: equilibrium ladder 2. A ladder leans against a wall in static equilibrium. Ladder, wall, and ground are perfectly rigid. The ladder has mass m ladder , length ladder , and center of located at cm along its length measuring from its base. The angle between the ladder and the VERTICAL is . HINT: Draw a good diagram marking on all possible forces: gravity, the normal forces of the ground and wall, and the friction forces of the ground and wall. Draw the ladder leaning to the right so that we are all consistent....
