Figure Q1a shows a bracket that can roll and move horizontally along a beam. A 1600 N force at 15° relative to the horizontal axis acts at A.  a)   Determine the force P at 25° relative to vertical axis necessary to keep the bracket static;   b)    Calculate the downward resultant force acting vertically at A. Assume coplanar forces.

See image for question. Thanks.

Show all work: indicate your plan and draw FBD's (Free Body Diagrams), write/label (symbolic) equations (e.g., ZFx = 0) before writing numeric equations, box answers. 1. A 100-lb vertical force is applied to the end of a lever, which is attached to a shaft at O. Determine a) the moment of the 100-lb force about O; b) the horizontal force applied at A that creates the same moment about O; c) the smallest force applied at A that creates the same moment about O; d) how far from the shaft a 240-lb vertical force must act to create the same moment about O; e) whether any one of the forces obtained in parts b, c, or d is equivalent to the original force. 24 in. 60° 100 lb
