To make a lever, you need a rigid bar or beam, a fulcrum (a fixed point on which the lever pivots), and a load or force being applied to one end of the lever.
A lever requires a rigid bar or beam, a pivot point called a fulcrum, and an effort force applied to one end in order to perform work. These components enable the lever to amplify or redirect the force applied to move an object.
The components of a lever include a rigid bar, also known as the lever arm, a pivot point called the fulcrum, and the input and output forces. The input force is the force applied to the lever to produce motion, while the output force is the force generated at the opposite end of the lever.
Some things that belong to a lever include a fulcrum (the pivot point), an effort force (the force applied to move the lever), a load force (the resistance being moved), and the lever arm (the distance between the fulcrum and where the forces are applied). Lever examples include a seesaw, crowbar, and a pair of scissors.
The length of the lever arm and the placement of the fulcrum can affect how easy it is to use a lever. A longer lever arm provides more mechanical advantage, making it easier to lift or move objects. Positioning the fulcrum closer to the load can also make it easier to use a lever by reducing the effort required.

the hand lever is the part of microscope.... the microscope need to see the small things or viruses....
You just need 2 things- your brain and your eyes.
Sunlight Air Water energy
a lever is used for helping people work with things.
Move things.
The four parts are: 1.Lever arm 2.Fulcrum 3. Effort 4.load
Fo four-hi just pull the transfer shift lefer back you should NOT need to push in the button on the lever. For four-low PUSH and hold the button, on mine I have to turn the engine off and pull the transfer shift lever to the four-low position.
The four thing you need to stay alive are: Oxygen, water, Food, and Air
FOOD, WATER, SUNLIGHT, AND SUNLIGHT
ummmmmmm.....you would'nt
Im sure you mean what four things you need when building a fire?? Anyways the answer is Oxygen,Match,Fuel,Timber
