Calculating tension

  1. Oct 26, 2004 #1
    Can anyone direct me to a website or something that deals with tension, some examples and how to calculate it? I don't get it... like if you have a mass held up by two strings what information do you need to calculate the mass, and how do you go about doing it? Thanks!

    If the system is in equilibrium, then you just need to resolve forces horizontally and vertically and then that will give you a set of simultaneous equations to solve.

    You should probably consider reading a very elementary textbook on general physics (or mechanics such as Resnick and Halliday/Sears+Zemansky, etc.) There are websites on the internet but all you need is a proper conceptual understanding of Newton's Laws and (in some cases) a certain degree of mathematical familiarity with things like simultaneous equations, algebra and calculus. Have a look at www.lightandmatter.com for some help.

    Are you talking about a pulley system?

    If you have acceleration, you can create two forces equations for both masses. Then you add them (or w/e else u want) to equate them and solve for m2.
