# A balanced lever has two weights on it, the first with mass #7 kg # and the second with mass #3 kg#. If the first weight is # 2 m# from the fulcrum, how far is the second weight from the fulcrum?

To find the distance of the second weight from the fulcrum, use the formula for a balanced lever:

( \text{Mass}_1 \times \text{Distance}_1 = \text{Mass}_2 \times \text{Distance}_2 )

Substitute the given values:

( 7 \times 2 = 3 \times \text{Distance}_2 )

Solve for ( \text{Distance}_2 ):

( \text{Distance}_2 = \frac{7 \times 2}{3} = \frac{14}{3} ) meters

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.

- How much work does it take to raise a #2 kg # weight #12 m #?
- An object with a mass of #24 kg# is hanging from an axle with a radius of #24 m#. If the wheel attached to the axle has a radius of #72 m#, how much force must be applied to the wheel to keep the object from falling?
- An object with a mass of #2 kg# is hanging from an axle with a radius of #2 cm#. If the wheel attached to the axle has a radius of #15 cm#, how much work would it take to turn the wheel a length equal to the circumference of the axle?
- A spring with a constant of #5 (kg)/(s^2)# is lying on the ground with one end attached to a wall. An object with a mass of #5 kg # and speed of # 7 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
- A balanced lever has two weights on it, the first with mass #3 kg # and the second with mass #27 kg#. If the first weight is # 6 m# from the fulcrum, how far is the second weight from the fulcrum?
