A lever is a rigid object used to make it easier to move a large load a short distance or a small load a large distance. There are three classes of levers, and all three classes are present in the body  . For example, the forearm is a 3rd class lever because the biceps pulls on the forearm between the joint (fulcrum) and the ball (load) Where is the fulcrum of this lever? Circle and label its location on the diagram above Read the excerpt from Exploring Mars. But that hasn't stopped the stories. Some people still believe that extraterrestrials built the face. Others s A lever is a simple machine made of a rigid beam and a fulcrum. The effort (input force) and load (output force) are applied to either end of the beam. The fulcrum is the point on which the beam pivots. When an effort is applied to one end of the lever, a load is applied at the other end of the lever. This will move a mass upward If the fulcrum (F) is in the middle it is a first class lever. If the resistance force (R) is in the middle it is a second class lever. If the effort force (E) is in the middle it is a third class lever. 1.

The applied force, or effort, is used to move a resistance, or load. In the human body, the joints are fulcrums, and the bones act as levers. Muscle contraction provides the effort that is applied at the muscle's insertion point on the bone

• Levers are classified according to the location of the fulcrum relative to the input and output forces. Draw the 3 classes of levers and label the fulcrum, input force, and output force. Include real-life examples for each class . edge of a circle to the circle's center The turning effect depends on the magnitude of the force, its location with respect to the center of rotation (the fulcrum), and the direction in which the force is applied. The location of the fulcrum is arbitrary; we shall see that the careful location of the fulcrum can simplify the solution of many rotational mechanics problems A lever has three points of interest: the fulcrum, the load, and the effort. The fulcrum is the point around which the lever pivots rotationally. The load is what we wish to manipulate with the lever, and the load is described by magnitude, direction, and position relative to the fulcrum

A lever (/ ˈ l iː v ər / or US: / ˈ l ɛ v ər /) is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum.A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types.Also, leverage is mechanical advantage gained in a system. . It is one of the six simple. 1. RED ARROW: The location and direction of the force (Fm). 2. GREEN ARROW: The location of the load or resistance (Fr). 3. BLUE CIRCLE: The location of the fulcrum. 4. BLACK LINE: The lever arm. 5. TYPE: Specify the type of lever. In the right hand column: 1. DRAW a sketch of the object. Repeat these observations and manipulations for each object 5. Draw a first-class lever system. If 150 lb is 1 foot away from the fulcrum, what force, applied 1 foot from the fulcrum, is required to lift the weight? Draw a diagram of the activity including all forces. What force is required to lift the same load if the lifting force is applied 2 feet from the fulcrum The Class of Lever is determined by the location of the load, fulcrum, and force. In a Class Three Lever, the Force is between the Load and the Fulcrum. If the Force is closer to the Load, it would be easier to lift and a mechanical advantage. Examples are shovels, fishing rods, human arms and legs, tweezers, and ice tongs. A fishing rod is an.

6. A lever simple machine consists of a load, a fulcrum and effort (or force). The load is the object that is moved or lifted. The fulcrum is the pivot point, and the effort is the force required to lift or move the load.

CENTER OF GRAVITY: The point in any solid where a single applied force could support it; the point where the mass of the object is equally balanced. The center of gravity is also called the center of mass The location of the fulcrum helps determine how well the lever will perform work.
