Just to clarify, if a string has a threshold of 100N, can the string be bent so that the tension in different parts individually doesn't exceed 100N yet the total force of the tensions do? My question arises because of this question: http://imgur.com/90NGY5p http://imgur.com/ObRq5QM Essentially, in this question, the string is bent and has 2 different nodes and there are 3 tensions analyzed. The maximum tension the string can withstand is 100N and if you look at the solution, the individual components do not exceed 100 N, yet the sum of them do. Just wondering, is this allowed? I always thought the TOTAL tension the string could withstand is 100 N, and the solution for this questions says otherwise. Any help with the problem would be great!
