Homework Help: physics

Posted by Dem on Tuesday, April 9, 2013 at 2:18pm.

In a modern art exhibit, a multicolors empty industrial wire spool is suspended from two light wires as shown. (Pic) The spool has a mass of 50 kg with an outer diamter of 75 cm and an inner exle diameter of 18 cm. One wire (#1) is attatched tangentially to the exle and makes a 10 degree angle with the verticle. The other wire (#2) is attatched tangentially to the outer edge and makes an unknown angle theta with the vertical. determine the tension in each wire and the angle theta.

* I believe you would solve by using a torque formula and net force? t=rFSin(Theta) perhaps?
