A balanced lever has two weights on it, the first with mass #9 kg # and the second with mass #4 kg#. If the first weight is # 3 m# from the fulcrum, how far is the second weight from the fulcrum?
Nathan AshcroftSummation of Moments about the fulcrum equals to zero.
Taking clockwise positive
God bless....I hope the explanation is useful.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A balanced lever has two weights on it, the first with mass #6 kg # and the second with mass #4 kg#. If the first weight is # 5 m# from the fulcrum, how far is the second weight from the fulcrum?
- A ball with a mass of #240 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #12 (kg)/s^2# and was compressed by #1/2 m# when the ball was released. How high will the ball go?
