1. The problem statement, all variables and given/known data A 10-m uniform beam of weight 100 N is supported by two ropes at its ends. If a 400 N person sits at 2.0 m from the left end of the beam, what is the tension in the left rope? I thought the answer would be: 3. The attempt at a solution 100*5 + 400*7 = T*10 3300 = T*10 T = 330 N But it's not correct. What am I doing wrong? Also: A book weighs 6 N. When held at rest above your head the net force on the book is? I say -6 N. Is this correct? Thanks!
