Homework Help: Physics: Statics Problem

  1. Jan 27, 2005 #1
    Hey, I'm having a lot of trouble with this physics homework problem:
    The cords BCA and CD can each support a max load of 100 lbs. Determine the max weight of the crate that can be hoisted at constant velocity, and the angle theta for equilibrium.

    The picture shows B attached to a pulley on the ground, rising up to point C which is a second, higher pulley suspended by a rope anchored from above at point D. Dropping to the other side of the pulley is the remainder of the rope from B to C, which happens to be point A, suspending a crate. The angle between the rope segment BC and the ground (x axis) is 67.4 degrees. The unknown angle, theta, is the angle that rope segment CD makes with the x axis.

    I really hope my description of the picture made sense. Can anyone help me get started?
