Question

Even though third class lever does not multiply the forces ,it is in practice ?

Answer 1

Third class lever mechanical advantage.The mechanical advantage is less than one.Third class levers don't multiply force they multiply distance.

MA=Input distance/Out put distance trade offs.The effort is between the resistance and the fulcrum.The third class lever always decreases the effort force.Distance is increased at the expense of force.Useful makes the production of machines possible.Used to hit an object with as much velocity as possible.Examples Stapler.
