1. The problem statement, all variables and given/known data This is just a more generalized question, and not really about a specific value. The question was regarding torque, and had a man standing on a ladder like so. The only force (exerted by the man on the ladder) that provided torque was indicated to be mg, but I don’t really understand—why isn’t Fn included? Obviously there is a downwards Fn exerted by the man on the ladder, so why doesn’t the diagram account for that? (I’m a bit confused since in loop-the-loop roller coaster problems, we always have to account for downwards Fn.) Thank you in advance!
