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 would it take to push a # 8 kg # weight up a # 1 m # plane that is at an incline of # pi / 4 #?
- A balanced lever has two weights on it, the first with mass #5 kg # and the second with mass #3 kg#. If the first weight is # 6 m# from the fulcrum, how far is the second weight from the fulcrum?
- A wrench with a length of #25 cm# is used to unscrew a #3/2 cm# bolt. If a torque of #1 Nm# is needed to overcome the friction keeping the bolt in place, what is the minimum torque that must be applied to the wrench to unscrew the bolt?
- The force applied against an object moving horizontally on a linear path is described by #F(x)=2x +4 #. By how much does the object's kinetic energy change as the object moves from # x in [ 3, 5 ]#?
- How much work does it take to raise a #7 kg # weight #23 m #?
