A uniform cable weighing 3 lb/ft is held in the position shown by a horizontal force P applied at B . Knowing that P = 180 lb and 0A= 60°, determine (a) the location of point B, (b) the length of the cable.
Knowing that the tension in cable AC is 300 lb, determine the smallest angle between cable AC and the boom AB.

In order to unscrew the tapped faucet A , a plumber uses two pipe wrenches as shown. By exerting a 40-lb force on each wrench at a distance of 10 in. from the axis of the pipe and in a direction perpendicular to the pipe and to the wrench, he prevents the pipe from rotating, and thus he avoids loosening or further tightening the joint between the pipe and the tapped elbow C . Determine (a) the angle 0 that the wrench at A should form with the vertical if elbow C is not to rotate about the vertical, (b) the force-couple system at C equivalent to the two 40-lb forces when this condition is satisfied.
