Unformatted text preview: Note regarding the angle: If the angle between the force vector and vector from axis to point where force is applied is ø, then the torque is F*r*sinø. However, in this problem, the angle is given as 30º from the *horizontal*, but the force (weight) is *vertical*, so the angle is 90º - ø, and the torque becomes F*r*cosø. http://answers.yahoo.com/question/index;_ylt=AuQ6QmYMi2EOSrbuUQvrI2cjzKIX;_ylv=3? qid=20071207004620AArN5lC...
