Homework Help: Physic

Posted by Mary Pinzon on Sunday, November 4, 2012 at 9:26pm.

Can some one help me with this question.

A uniform 119.0 cm long, 78.0 gram wooden rod is suspended from it midpoint. On one end of the rod, a mass of 350 g is attached, and on the other end a mass of 150 g is attached. A third mass of 225 g is attached at some distance x from the midpoint such that the rod does not rotate. Assume all of the masses hang perpendicular to the rod. Determine the distance x in cm.


I have tried torque 350g = T225 +T150 to solve but I am not getting the right answer.

Thank you for your help!
