  • ltbrltgt A string of mass m (can be non uniform as well) is suspended through two points which are not in same horizontal level. Tension in the string at the end points are T_(1) and T_(2) and at the lowest point is T_(3) . Mass of string in terms of T_(1),T_(2) and T_(3) can be represented a (uniform gravity 'g' exists downwards)

    A
    `(sqrt(T_(1)^(2)-T_(3)^(2))+sqrt(T_(2)^(2)-T_(3)^(2)))/(g)`
