When I use a lever, I can lift heavier stuff. Where exactly does that additional force come from? Was it inside me all the time, or does it come from somewhere outside of me?

When I use a lever, I can lift heavier stuff. Where exactly does that additional force come from? Was it inside me all the time, or does it come from somewhere outside of me?

Answer 1

torque- the longer the radius of the lever is, the less force is required to generate the same amount of torque (turning force) . so basically, you can apply the same amount of force to something with a 30 centimeter lever and a 60 centimeter lever, and have a lager amount of torque on the 60 centimeter lever
