# How does a bottle opener use principle of levers? watch

1. Im trying to do some research on how bottle openers use the principle of levers for physics gcse but only thing that is coming up are tops and tricks and nothing which is useful.
Could someone pls help and tell me how it uses levers?
If you used a website could you give the link so I can check it out pls?
Thanks!

3. Thank you!!!

4. F is the fulcrum (pivot), E is the effort (input force), and R is the load (output force). Because the fulcrum is on the opposite side of the effort, it is a second-class lever. These are designed to have mechanical advantage (Load / Effort), which means they reduce the amount of force you need to use, by increasing the distance in M = F x D.

Hope I helped!
