1. The problem statement, all variables and given/known data Homogenous beam rests on smooth wall such that it forms an angle of 60 degrees with the ground (picture is rotated). A body of mass m = 60 kg rests 7 m from the end of beam which lies on ground. Mass of beam equals 15kg and length equals 10 m. What is the minimal friction factor such that beam remains in same position? 2. Relevant equations Torque = Force x distance 3. The attempt at a solution I guess that total moment needs to be 0 but I can't go further then that. Also I don't know what the center should be. I know that the forces are gravitational of body, beam, and friction of beam and ground.
