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 #1 kg# is hanging from an axle with a radius of #16 m#. If the wheel attached to the axle has a radius of #8 m#, how much force must be applied to the wheel to keep the object from falling?
- If a rocket with a mass of 3900 tons vertically accelerates at a rate of # 7/8 m/s^2#, how much power will the rocket have to exert to maintain its acceleration at 5 seconds?
- An object with a mass of #2 kg# is hanging from an axle with a radius of #2 m#. If the wheel attached to the axle has a radius of #6 m#, how much force must be applied to the wheel to keep the object from falling?
- How much work would it take to push a # 6 kg # weight up a # 7 m # plane that is at an incline of # pi / 4 #?
