Any solid material that can stand its' weight plus the object to lift.
Wood, Iron, Concrete, Plastic, Rock or even Ice block can do the job.
There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.
it help us us because it lessen our force
Levers. Mostly levers.
Levers make life easier by allowing us to lift or move heavy objects with less effort. By using a fulcrum, levers amplify force, enabling a smaller input force to generate a larger output force. This mechanical advantage reduces the physical strain on our bodies, making tasks like lifting, prying, or pushing much more efficient. Overall, levers enhance productivity and ease in various everyday activities.
Common compound machines found in homes and schools include scissors, which combine levers and wedges to cut materials, and can openers, which utilize levers and wheels to remove lids from cans. Other examples are staplers, which use levers and wedges to fasten papers together, and pulley systems used in window blinds. Additionally, bicycles combine levers, wheels, and gears to facilitate movement. These machines simplify tasks by using multiple simple machines in conjunction.
do levers make doing work easier

Levers can be made from various materials such as wood, metal, plastic, or composite materials. The choice of material depends on factors like the intended use, load-bearing capacity, and durability required for the lever's application.
Make sure you have a lot of used materials, such as cardboard, pulleys, levers, screws, wood, marbles, and anything else. Use the parts to make your machine.

you need bits and peices of things
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.
well they were really poor so they need to make all materials
Levers and Leverage can be used in a variety of forms to make life easier.Door Handles on a car are essentially levers connected to levers via various linkages.You will find several levers on a bicycle. Your cranks, shifters, and brakes are all levers. Derailleurs have a few levers in them, and perhaps the handlebars are a unique type of lever too.
Levers are a big deal when it comes to Mouse Trap Cars, levers help make the mechanical advantage and ideal mechanical advantage higher and better.
