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 , then the torque is F*r*sin. However, in this problem, the angle is given as 30 from the *horizontal*, but the force (weight) is *vertical*, so the angle is 90 - , and the torque becomes F*r*cos. http://answers.yahoo.com/question/index;_ylt=AuQ6QmYMi2EOSrbuUQvrI2cjzKIX;_ylv=3? qid=20071207004620AArN5lC...
