leva

macchina semplice costituita da un'asta e un fulcro

AI overview

A lever is a simple machine made from a rigid rod that pivots on a fixed point called a fulcrum, allowing it to rotate and lift or move objects. It works by amplifying the force you apply to it, so you can move or lift something heavier than you could with your bare hands alone.

La leva è una macchina semplice che non converte l'energia, ma moltiplica la forza applicata alla leva. È costituita da un'asta rigida capace di muoversi attorno a un punto fisso, chiamato fulcro; è un'applicazione del principio di equilibrio dei momenti.
