One more question

Ok, I was giving this question about levers:

What is the ideal mechanical advantage for each of the three lever systems?
The three lever systems are the basic ones, and there is no numbers. It is just a question asking for explaination.

Thanks

The first type of lever can have either a force or a speed advantage depending on where you put the fulcrum. Type 2 is always a force advantage. Type 3 is always a speed advantage.
