I am having difficulty with tensions and pulleys. Can someone give a good explanation of how they work and what are some rules to solve the problems I have for homework. As far as I can see, the book and the instructor is not that good in describing this topic Here is one example of a problem: A picture hangs on the wall suspended by two strings as seen in the figure 6-20(see below for a written explanation). The tension in string one is 1.7N. (a) is the tension in string 2 greater than, less than or equal to 1.7N (explain) (b)verify your answer by calculating the tension on in string 2 (c) what is the weight of the picture? In the example there is a pictrue hanging in the middle of two strings, one string string one in 65degrees above the -X axis and string 2 is 32degrees above the X axis. Here is what I have done: T1x = 1.7(-cos115degrees) T1y = 1.7(sin115 degrees) and that is it...HELP!!
