it is a simple machine with a point on it called the fulcrum
it help us us because it lessen our force
Simple machines such as levers and pulleys can make work easier for us.
do levers make doing work easier
Levers can make exercise more difficult depending on how they are used. They can help to make the resistance stronger so a muscle has to work harder.
Levers help us in life by allowing us to exert a smaller force over a longer distance to move a heavier object. They provide mechanical advantage by leveraging the force applied, making tasks easier to perform. Levers are found in many everyday objects such as doors, scissors, and wheelbarrows, making them essential tools in various aspects of our lives.
levers work by having a effort that lifts a load, and a fulcrum balances the two
Levers are simple machines that help move objects by applying force at a certain point. They work by using a rigid bar or beam to exert force on an object to lift, push, or pull it. There are three classes of levers based on the relative positions of the effort force, the load, and the fulcrum.

Archimedes work on levers brought about the concept of torque. He used levers and pulleys to illustrate mechanical advantage. Torque and moments make us understand the mechanical concepts.
Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!! Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!!I always found it interesting that there are three classes of levers:1st class: The exerted force (Fe) is on the opposite side of the fulcrum (F)of the resulting force (Fr). For example, a pry bar.Fe-----F-----Fr2nd class: For example, a wheelbarrow:F-----Fr-----Fe(the fulcrum is the wheel)3rd class: For example a baseball batFr-----Fe-----F(the fulcrum is your hand)A fingernail clipper is a compound lever. It has a 2nd class and a 3rd class.A see-saw provides good fun. Although you might not think so your knives, forks and spoons are levers. You have the brake and gear change levers on a cycle. You might not be aware that there are three basic types of levers. Many switches are levers. Your own body has quite a few "bone" levers. When you flick a small ball of paper by using your ruler you are using a lever. You use a lever called a spoon to stir with. A bedroom door is a lever, as are most hinged things.Increasing force by mechanical advantage.>Mechanical advantage = distance moved by input / distance moved by output>Output force = input force * mechanical advantage>Force * distance = work done>(Input) force * distance = (Output) force * distance
Yep! I am not sure what class but it is! Levers help lift heavy objects. Levers work by the farther you are from the fulcrum or pivot as compared to the heavy objects, the lesser the force you will need to lift or pull the object.
