Mechanical Advantage
Early humans have been making tools from stone since the Stone Age. As we became more evolved, humans became creative in the use of tools and machines. But why do we use tools? Sure, it must make life or work easier; there must be some kind of advantage to using tools and machines.

-
Mechanical advantage can be expressed as output force (F1) / input force (F2). Especially for lever systems, mechanical advantage can also be expressed in terms of distance using the torque principle formula above.
