I have one question about the balancing force. Please help. Find the tension (T1, T2) of each string. Please see the figure. My answer: Set T2 as pivot. 30 * 0.2 = 20 * 0.3 + 20 * 0.6 - T1 * 0.4, solve for T1 Set T1 as pivot. 30 * 0.6 - T2 * 0.4 + 20 * 0.1 = 20 * 0.2, solve for T2 If any problem with my answer, please tell. Now, if the breaking tension of each string is 50 N, find what weight of A should be when one of the strings breaks. State which string will break first and why? Don't know how to solve and explain. Please give me some help.
