An optical lever works by using a laser beam and a mirror attached to the system being measured. As the system moves, it changes the angle of reflection of the laser beam on the mirror. By measuring this change in the laser beam's position, the displacement of the system can be accurately determined.
An optical lever is used because it magnifies small changes in length, making it easier to detect the expansion of the metal tube. The lever amplifies the displacement of the marker on the tube, allowing for more precise measurement of thermal expansion. This method provides accurate and reliable results in determining the expansion coefficient of the metal.
The efficiency of a lever can be calculated using the formula: Efficiency = (output force × output distance) / (input force × input distance) * 100%. It represents the ratio of the output work done by the lever compared to the input work applied to the lever.
To calculate the work input of a lever, you can use the formula: work input = effort force x effort distance. The effort force is the force applied to the lever, and the effort distance is the distance the effort force acts over. Multiply these values to find the work input.
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.
The force applied to a lever is called the effort force. This force is used to overcome resistance at the load end of the lever in order to perform work.
It is massless and it is not affected by gravity.
a lever is used for helping people work with things.

As many as you think work!

The lever. Wheels work the same way that a lever does in that a wheel is like the outer end of the lever...
"Optical", in this case, simply means that they work with light.
Scientists and kids for their work
Sure, as a work of art.

This isn't that kind of carjack that you guys think it is, it a kind of tool for a car. It makes work easier because you can use it as a lever. You can use it as any kind of lever, a first class lever, a second class lever, ora third class lever. It works better as a third class lever. It works better as a third class lever because your using less work. Less work is being done with a third class lever because of he distance. The more the distance, the less force you need. Also, the more the distance, the less heavier it is.
