Mechanical advantage is not the only reason to use levers.
Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
Mechanical advantage=load/effort
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call an estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less.

The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle.
Mechanical advantage is not the only reason to use levers.
No, not all levers have a mechanical advantage. The mechanical advantage of a lever depends on the specific positions of the effort, load, and fulcrum. Some levers may have a mechanical advantage of less than 1, resulting in a decrease in force but an increase in distance.

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.
Most of the levers in the body are third-class levers because they prioritize speed and range of motion over force production. These levers allow for quick and efficient movement by placing the effort arm (muscle force) between the fulcrum and the resistance (load). While they do not provide a mechanical advantage in terms of force, they are well-suited for precise and coordinated movements required in activities like sports and everyday tasks.
Second class levers have the load between the fulcrum and the effort (load-fulcrum-effort), while third class levers have the effort between the load and the fulcrum (load-effort-fulcrum). Second class levers provide mechanical advantage and are more efficient for lifting heavy loads, while third class levers provide a speed advantage but require more effort.
They don't, they just give you a mechanical advantage.
In the body, joints act as the fulcrum when bones function as levers. Joints provide a pivot point around which bones can move to generate mechanical advantage for various movements.
Class two levers provide a mechanical advantage by having the load situated between the fulcrum and the effort. This means that a smaller effort can be used to lift a larger load. Examples of class two levers include a wheelbarrow and a bottle opener.
Common mechanisms for obtaining mechanical advantage would include such as multiple pulleys, hydraulic systems, gears, and levers.
The mechanical advantage of the lever is that smaller persons can move heavier objects. The lever can be placed under the object and the person can then push down on the lever.
