If one is only considering the mechanics of a lever, what is the maximum
a physically possible lever can lift ?
a physically possible lever can lift ?
KingNothing said:Wolram - I suspect you are nudging at the question of whether having a circular force (torque) has any significance on the material limits?
A lever is a simple machine that consists of a rigid bar or rod that is able to pivot or rotate around a fixed point called the fulcrum. It is used to multiply or change the direction of a force, making it easier to lift or move objects.
The practical limits of a lever refer to the factors that affect its efficiency and effectiveness in lifting or moving objects. These limits include the length of the lever, the placement and strength of the fulcrum, and the weight and position of the load being lifted.
The length of a lever determines the amount of force that can be applied to lift or move an object. The longer the lever, the greater the distance between the applied force and the fulcrum, resulting in a larger mechanical advantage and easier lifting or moving of objects.
The fulcrum is the fixed point around which the lever rotates. Its position and strength determine the efficiency of the lever. Placing the fulcrum closer to the load reduces the effort needed to lift it, while placing it closer to the applied force increases the distance the lever needs to be moved.
Levers are used in many everyday objects and tools, such as scissors, pliers, seesaws, and wheelbarrows. They are also used in larger applications, such as cranes, forklifts, and construction equipment. In the human body, bones and joints act as levers to help us move and perform tasks.
