How Does a Lever Work and What Can It Do?
A lever is a simple machine that consists of two material components and two work components: The beam is placed so that some part of it rests against the fulcrum. In a traditional lever, the fulcrum remains in a stationary position, while a force is applied somewhere along the length of the beam. The beam then pivots around the fulcrum ...
Lifting with a Lever | Lesson Plan
A lever is a type of simple machine that can be used to increase a force. A lever consists of a beam attached to a pivot (called the fulcrum). A lever allows you to take an input force (the effort) and amplify the output force (the load). A seesaw at the playground is a simple example of a lever. Imagine that you have three children who are all ...

Lever | Definition, Types & Examples
A lever is a simple machine that contains 3 parts: a fulcrum (pivot point), an effort (input force), and a load (output force). Levers are classified by the position of the fulcrum within the system.
Types of Lever
A lever is a simple machine consisting of a rigid bar or beam that is capable of rotating around a fixed point called a fulcrum. Levers are commonly used to amplify or redirect force, allowing for easier movement or manipulation of objects. Levers are of three types, first class levers, second class levers, and third class levers.
Examples of Simple Machines & Complex Machines
Scissors: Making the Cut. As a machine, a pair of scissors seems pretty simple, though it's actually a complex machine. A scissors combines two levers with the cutting action of the wedge. The levers multiply the force on the object to be cut, making it easier to use and more effective than a knife.

Lever (article) | Discoveries and projects | Khan Academy
You could use a ruler and a slim pencil rubber. The advantage of using a ruler is that you can literally measure the distances as you change the mechanism! And the rubber won't let the ruler slide apart, but remeber that it has to be slim, otherwise it won't represent a fulcrum. As for the weight, some coins will do the job.
Types Of Lever
First Class Lever. This is a type of lever which has the fulcrum in between the weight and the force applied. Its order is represented as force-fulcrum-weight. This is the most basic type of lever. Example: Our hand pushing an object or seesaws, crowbars. Using scissors represents the use of two first-class levers.
15 Compound Machines Examples Used in Day-to-Day Life

It comes with two simple machines named a wedge and a lever. The blades of scissors look wedge-shaped and the handles come to act like first-class levers. 2.
9.5 Simple Machines
Simple machines are devices that can be used to multiply or augment a force that we apply – often at the expense of a distance through which we apply the force. The word for "machine" comes from the Greek word meaning "to help make things easier." Levers, gears, pulleys, wedges, and screws are some examples of machines.
Compound Machine
It is used to carry heavy objects. It consists of two simple machines: a lever and a wheel and axle. Effort is applied to the lever by picking up the handles of the wheelbarrow. The lever, in turn, applies upward force to the load. The force is increased by the lever, making the load easier to lift. Effort is applied to the wheel of the ...

1. Nut Cracker. A nutcracker is a prominent example of a second-class lever simple machine. Here, the fulcrum is located at one end of the machine, and the load or the nut, in this case, is placed in the middle. The force required to break the nut is applied to the end that is present opposite to the fulcrum. 2.
Simple machines/Lever
A wheelbarrow is a second-class lever. The wheel's axle is the fulcrum, the handles take the effort, and the load is placed between them. The effort always travels a greater distance and is less than the load. Second class lever: Brown= fulcrum; Third class lever: Third-class levers have the effort placed between the load and the fulcrum.

6 Kinds of Simple Machines
A lever is a simple machine that consists of a rigid object (often a bar of some kind) and a fulcrum (or pivot). Applying a force to one end of the rigid object causes it to pivot about the fulcrum, causing a magnification of the force at another point along the rigid object. There are three classes of levers, depending on where the input force ...
