- Class 1: Fulcrum in the middle: the effort is applied on one side of the fulcrum and the resistance on the other side, for example, a crowbar or a pair of scissors.
- Class 2: Resistance in the middle: the effort is applied on one side of the resistance and the fulcrum is located on the other side, for example, a wheelbarrow, a nutcracker, a bottle opener or the brake pedal of a car. Mechanical advantage is greater than 1.
- Class 3: Effort in the middle: the resistance is on one side of the effort and the fulcrum is located on the other side, for example, a pair of tweezers or the human mandible. Mechanical advantage is less than 1.

What is the fulcrum called at the end with the load in the middle?
The fulcrum can only ever be called the fulcrum. You may be asking about the three classes of levers: if so, you need to ask the question with enough description to allow an answer.
What are some class 1 levers?
Lever belongs to the category of simple machines. They are three types of levers 1. First class levers 2. Second class levers 3. Third class levers In the first class levers fulcrum is in between applied force and load. common examples are Crowbar , Pair of scissors , SeeSaw , Skull and neck in our body .
What are the description of lever?
A lever is a simple machine that makes work easier for use; it involves moving a load around a pivot using a force. Many of our basic tools use levers, including scissors (2 class 1 levers), pliers (2 class 1 levers), hammer claws (a single class 2 lever), nut crackers (2 class 2 levers), and tongs (2 class 3 levers).

Classification of levers?
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.

Working model based on any principle of physics?
You can make foam balls on speaker output Model . This will be related to sound. You can make a little tiny see-sawwith a movable pivot, and use it to illustrate the three classes of levers, and to demonstrate how work energy is conserved in the operation of levers.
How many levers and what classes of levers are in a nail clipper?
first class The point about which a lever rotates is called the fulcrum
Do levers make work easier?

on the position of the fulcrum
What is some information about levers?
Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!! Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!!I always found it interesting that there are three classes of levers:1st class: The exerted force (Fe) is on the opposite side of the fulcrum (F)of the resulting force (Fr). For example, a pry bar.Fe-----F-----Fr2nd class: For example, a wheelbarrow:F-----Fr-----Fe(the fulcrum is the wheel)3rd class: For example a baseball batFr-----Fe-----F(the fulcrum is your hand)A fingernail clipper is a compound lever. It has a 2nd class and a 3rd class.A see-saw provides good fun. Although you might not think so your knives, forks and spoons are levers. You have the brake and gear change levers on a cycle. You might not be aware that there are three basic types of levers. Many switches are levers. Your own body has quite a few "bone" levers. When you flick a small ball of paper by using your ruler you are using a lever. You use a lever called a spoon to stir with. A bedroom door is a lever, as are most hinged things.Increasing force by mechanical advantage.>Mechanical advantage = distance moved by input / distance moved by output>Output force = input force * mechanical advantage>Force * distance = work done>(Input) force * distance = (Output) force * distance
How do levers work?
levers work by having a effort that lifts a load, and a fulcrum balances the two
