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.

- An object with a mass of #300 kg# is hanging from an axle with a radius of #3 cm#. If the wheel attached to the axle has a radius of #81 cm#, how much work would it take to turn the wheel a length equal to the circumference of the axle?
- The force applied against a moving object travelling on a linear path is given by #F(x)=x^2+x #. How much work would it take to move the object over #x in [1,4 ] #?
- An object with a mass of #5 kg# is hanging from an axle with a radius of #15 m#. If the wheel attached to the axle has a radius of #3 m#, how much force must be applied to the wheel to keep the object from falling?
- How do you calculate the actual mechanical advantage of a lever?
- An object with a mass of #200 kg# is hanging from an axle with a radius of #8 cm#. If the wheel attached to the axle has a radius of #64 cm#, how much work would it take to turn the wheel a length equal to the circumference of the axle?
