What is the function of the fulcrum on a lever?
The fulcrum is the point of the lever where a change in motion will occur. There are 3 types of levers that are illustrated at this URL (http://i1131.photobucket.com/albums/m554/skyop22/Answers%20Pictures/levers.gif). The three types will distribute the load differently based on where the fulcrum is.
How is your thumb a lever?
A lever is simply a solid structure on which forces act. The human thumb is therefore made up of a number of classic levers. The joints make up the fulcrums, the tendons attachment points apply the effort, and the force is applied at the end of the thumb.
What is the difference between first class second class and third class levers?
the difference is the position of the fulcrum. a first class lever has the fulcrum between the lode and applied force. a second class lever has the load between the fulcrum and applied force. A third class lever has the applied force between load and fulcrum. The load happens to be the thing that you are affecting in the system. On a seesaw the load and applied force changes as either kid goes up, but the lower kid is always the force and upper is the load with the fulcrum in the middle. this happens to be a first class lever. a second class lever could be a bottle cap opener with the fulcrum at the end the bottle cap(load) in the middle and you pushing (force) on the other. a third class lever are like tweezers with the fulcrum on the closed end, force is you pushing in the middle, and affected load is whatever you pick up. There are also compound levers like nailclippers, but by diagramming the whole system it should be pretty easy to discover that it is a first class lever. It's compund because of the use of a lever system
What class of lever is a hole punch?
If you have the fulcrum ( unmoveable pivot point) between your hand and the object you are prying, it is a 1st class. If the end of the pry bar is wedged into a fulcrum and you are trying to move something between the end of the bar and your hand, it is a 2nd class. My class used a pry bar as " a classic example of a 1st class lever"....sometimes true, but very common to use it as a 2nd class as well ( e.g. moving an alternator, etc...)
What class lever is a door knob?
second class lever
What are some examples of class 3 levers?
First class levers are like see-saws. The fulcrum (turning point) comes between the effort and the load. So if you push down on the effort the load goes up. With second class levers the load comes between the effort and the fulcrum. This is good for catapulting things. Third class levers have the effort between the load and the fulcrum. An example would be a fishing rod. The fish on the end is the load, your hand on the rod is the effort and the hand at the end is the fulcrum.
How do you connect second class levers?
like a wheel barrow effort on one side load in middle and fulcrum on other end
What do first class levers do?
First class levers change direction of force applied, like using a crow bar to open a door.In a first class lever, the fulcrum is between the force arm and the resistance arm. Seesaws, crowbars, and oars are first-class levers.
List 5 types of levers?
There are three types of levers.there is first class levers were the fulcrum is in the middle and the load and effort are on the sides.also there is second class levers were the load is in the middle and the effort and fulcrum are either of the sides.last but not least there is third class the effort is in the middle and the fulcrum and load are on any side. :)first class second classand third classclass 1 lever like a fork or hammer. class 2 lever like a nut-cracker or a door.. and a class 3 lever such as tweezers, or a golf club...
What are 10 examples for levers?
Well, there are three classes of levers. Class one levers are seesaws, where the effort force is on one end, fulcrum in the middle and object on the other end moving the opposite direction of the effort force. Class two levers are wheelbarrows, where the effort force is on one end, the fulcrum on the other and the object in the middle. Class three levers are like baseball bats, the fulcrum is on one end, the effort force in the middle and the object on the end. Other examples include: a golf club, catapult, an arm, a door, a tennis racket, a fly swatter or a stick.
What are the three kinds of levers?
The three kinds of levers are the: A) First-class lever - Like a seesaw, the fulcrum is in the middle. The input force is on one side and the output force comes out on the other side of the fulcrum. B) Second-class lever - This one is like a wheelbarrow. The fulcrum is all the way at the end, and you PULL upon the other end so the middle (where the bucket is) gets lifted up also. C) Third-class lever - The third class lever is like the second, but the input force is not at the end. The fulcrum is at one end, and on the other end is the output force. Its like the forearm of a human, our elbow is the fulcrum while you grip things with hand means you life some weight that is load and the arm is where you feel some effort being applied..

Which vitamin functions like a hormone?
Vitamin D functions like a hormone and controls body levels of calcium and phosphorus and the mineralization of bones
What do human bones do?
Bones serve several very important functions:Sites of attachment for muscles that move your body.Protecting valuable internal organs like the heart and lungsEncasing the central nervous system: the brain and spinal cordProviding the framework that supports the body.Acting as biomechanical levers to facilitate the movement of musclesThe long bones have marrow that can produce blood cellsCalcium and phosphorous are stored in the bones and released into the blood when needed.Many other smaller functions exist!
