1. The problem statement, all variables and given/known data (Please see attachment for the problem statement) https://www.physicsforums.com/attachment.php?attachmentid=27212&stc=1&d=1280270933 3. The attempt at a solution I do not see how we use the fact that the total torques balance when the rotational axis is through point A to find answer questions a) through d). I mean, every variables are unknown.... So! ANyone got a hint?
