the law for a second class lever is that the load is between the fulcrum and the effort
no, he did not !he explained how the lever works, the rule, the law, he did not invent it!
the bell crank lever is a apparatus used to verify the law of moments.
The law of the lever states that the effort multiplied by the effort arm equals the load multiplied by the load arm in a lever system, allowing for the calculation of mechanical advantage and equilibrium. This principle governs how force is applied and distributed in a lever system.
The law of the lever states that the product of the force and distance on one side of a lever is equal to the product of the force and distance on the other side. This means that the effort required to move an object on one side can be reduced by increasing the distance from the fulcrum on that side.

The law of the lever states that the product of the weight being lifted and its distance from the fulcrum is equal to the product of the force applied and its distance from the fulcrum. This principle was discovered by the ancient Greek mathematician and physicist Archimedes.
A lever arm balance is a simple machine that uses a lever arm to compare the weights of two objects. When the lever arm balances horizontally, it indicates that the weights on each side are equal. This principle is based on the law of equilibrium in physics.

Longer levers create a greater distance between the force applied and the pivot point, resulting in greater torque. This allows the lever to amplify the force applied to it, making it stronger compared to a shorter lever. This principle is known as the law of the lever in physics.
According to Archimedes, the principles of the lever include the Law of the Lever and the Principle of Virtual Work. The Law of the Lever states that the product of the weight being lifted and its distance from the fulcrum is equal to the product of the weight applied to the other end and its distance from the fulcrum. The Principle of Virtual Work states that if a lever is balanced and one side is moved along a circular arc, the distances of the weight and the weight applied to the other end from the fulcrum are inversely proportional to their magnitudes.
The simple machines - a lever for example - are usually designed so that you need less force. In compensation, you need to move the lever for a greater distance. This follows directly from the law of conservation of energy.
Newton's laws of motion can be applied to simple machines by analyzing the forces involved in the operation of the machine. For example, when using a lever, Newton's first law states that an object at rest will stay at rest unless acted upon by an external force. When the lever is in motion, Newton's second law explains the relationship between the force applied to the lever and its resulting acceleration. Newton's third law states that for every action force, there is an equal and opposite reaction force, which can be observed in the balance of forces within a simple machine.
