3. A 60 pound force is attached to the 90° weightless bar ABCD at point B as shown below. The bar is attached to the z axis at A and to the x-y plane at D by ball & socket joints. A cable EC attaches the bar to the y axis as shown. Determine the tension in cable EC. You might want to project something. Note that the ABC part of the bar lies in the x-z plane; that is, it is parallel to the x-axis. Hint: The answer is an integer between 10 and 50. y E
