In a first class lever the fulcrum is at the middle. load and effort are applied at two ends. eg scissors.
In second class lever fulcrum is at one end and effort is at other end. The load is at the middle. eg nutcracker.

There are 2 parts of a Lever mechanism: 1.) The lever (shaft) itself ... 2.) the Fulcrum.
Please see this example as below. <?php $first_variable = "Heloooo"; function first_method(){ print 'Heloooo'; } class firstClass{ public $testvar=""; function firstClass(){ // initialize $this->testvar = "Hiiiiiii"; } function first_method_inclass(){ print 'Heloooo'; } } ?>

When a lever is acted on at two different points by two different forces, the lever will experience a net torque calculated as the product of the force and the distance from the axis of rotation. The lever will rotate in the direction of the greater torque applied. The equilibrium condition is when the sum of the torques acting on the lever is zero.

because a lever gun has different levels that need to be put into it
The parts of a lever, such as the fulcrum, effort arm, and load arm, can be arranged in different configurations depending on where they are positioned relative to each other. This can affect the mechanical advantage and function of the lever. Experimenting with the placement of these parts can help optimize the lever for different tasks or to suit specific needs.
A lever and a pulley are different. They are both simple machines that have been around for over two thousand years and described in detail by a Greek named Archimedes.
