Hi please help!: A 12.8 m ladder whose weight is 200N is placed against a smooth vertical wall. A person whose weight is 500 N stands on the ladder a distance 2.2 m up the ladder. The ladder makes an angle of 31 degrees with the vertical wall (see figure)A.

A uniform, 255 NN rod that is 1.80 mm long carries a 225 NN weight at its right end and an unknown weight WW toward the left end ). When WW is placed 60.0 cmcm from the left end of the rod, the system just balances horizontally when the fulcrum is located 75.0 cmcm from the right end. Find WW. Express your answer with the appropriate units. If WW is now moved 25.0 cmcm to the right, how far must the fulcrum be moved to restore balance? Express your answer with the appropriate units.

A light triangular plate OAB is in a horizontal plane. Three forces, F1 = 6.0 N, F2 = 9.0 N, and F3 =7.0 N, act on the plate, which is pivoted about a vertical axes through point O.

One end of a meter stick is pinned to a table, so the stick can rotate freely in a plane parallel to the tabletop. Two forces, both parallel to the tabletop, are applied to the stick in such a way that the net torque is zero. The first force has a magnitude of 2.00 N and is applied perpendicular to the length of the stick at the free end. The second force has a magnitude of 6.00 N and acts at a 27.3o angle with respect to the length of the stick. Where along the stick is the 6.00-N force applied? Express this distance with respect to the end of the stick that is pinned.
