A ruler is not considered a lever. A lever is a simple machine that consists of a rigid beam that pivots around a point called a fulcrum, while a ruler is a measuring tool used to measure length or distance.
A ruler can be used as a lever by applying force to one end to lift or move objects. It can also be used as a straight edge to help draw straight lines or measure lengths accurately. Additionally, a ruler can be used as a fulcrum in conjunction with another object to create a pivot point for lifting or balancing tasks.
fulcrum
A lever pivots on its fulcrum, which is the fixed point where the lever rotates. The position of the fulcrum affects the mechanical advantage and function of the lever.
The fulcrum in a lever is the fixed point around which the lever rotates or pivots. It acts as the support for the lever and is essential for enabling the lever to work by providing a pivot point for the force applied on one end to lift or move an object on the other end.
A lever rests on a fixed point called the fulcrum. It is where the lever pivots or rotates when a force is applied to one end of the lever.
The simplest lever can be constructed with a ruler and an eraser. Place the ruler on top of the eraser and you have a lever. Many other objects can perform the same function
A marble is like a wheel: it rolls and also has height. The ruler is the lever, like a seesaw. Depending on the size and weight of what I want to lift, a marble and ruler could act as a lever. Levers assist us to do tasks.
Whether something is a lever depends on how you use it. The most obvious thing to use as a lever would be a ruler, but conceivably you could use a pencil in that way, and scissors are necessarily levers.
Simply take an eraser, then place a ruler or long thin piece of wood.Then rest a very small item -example-small stone, the slightly push down the clear side of the ruler or wood and thats a lever.

start out by finding a 12 inch wooden ruler. then find a cork or something that is similar to a rectangular prism to be the fulcrum. and bada-bing bada-boom a quick homemade ruler. hope this works. PEACE
When the plastic ball is placed on the ruler and the ruler is extended past the edge of the desk, it creates a lever system. As the weight of the ball causes the ruler to tip downward, the other end of the ruler, which is unsupported, rotates downwards due to gravity, launching the ball upward into the air. This action is a result of the principles of leverage and gravitational force.
The safety rule for using a ruler is to handle it carefully to avoid sharp edges and potential injury. Always ensure the ruler is placed flat on the surface before measuring to prevent slipping. Additionally, avoid using it as a lever or a tool for cutting, as this can lead to accidents. Always store it in a safe place when not in use to prevent damage and maintain its accuracy.
To take care of a ruler, store it in a dry place to prevent warping or damage. Keep it away from extreme temperatures and direct sunlight. Clean it regularly with a soft cloth to remove dirt and debris, and avoid using it as a lever or tool to prevent bending or breaking. If it’s a wooden ruler, consider applying a wood conditioner occasionally to maintain its finish.

A fulcrum in a lever is very important because without a fulcrum a lever isn't a lever , and the fulcrum is the main part of a lever.
