- (Refer to the figure below) How much must the object on the right weigh if the 200-N block is to remain at rest? The friction between the block and the incline is negligible and the pulley if frictionless.

Her crane has a 15K chassis and 35K counterweight. Assume all other parts of the crane have negligible weight. Answer all questions relative to the rotation point. How much torque is caused by the load? How much torque is caused by the chassis? How much torque is caused by the counterweight? What is the normal force on the rear (right) outriggers? What is the normal force on the front (left) outriggers? *each box in picture = 5 ft4. A uniform ladder 10m long and weighing 350N rests against a smooth wall at an angle of 30° with the wall.

- Help!! Be sure answer all clearly!Look at the following arrangement. Block A is held at rest on the frictionless wedge B by a massless rope that passes over a massless and frictionless pulley attached to the ceiling. The wedge sits on a scale. The wedge is not anchored in any way to the scale, and it is initially held at rest by a hand in such a way that the rope on the left of the pulley is oriented vertically. a) What is the scale reading after letting go of the wedge gently until the wedge comes to rest? b) What is the orientation of the rope after letting go of the wedge gently until the wedge comes to rest?
