A broom is an example of a class three lever because the effort is in the middle of the fulcrum and load
Example of third class levers are:
Some common class 2 levers are:
1.Stapler
2.Bottle opener
3.Wheel barrow
4.Nail clippers
5.Nut cracker

Yes, a hammer can be both a class-1 and a class-3 lever. Although, not all levers can be more than one class only some. For example, a hammer and a clothespin.

second class lever
•Hiqh efficiency. But range of motion and speed suffer. from a L.M.T.
It depends on the exact construction of the switch in question. Some are first class, some are second class, and some aren't levers at all.
it takes more force
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 .
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..
Happens that i am working on this right this moment in class, here you go, there are also some websites that our teacher gave us that can help to explain this: http://www.peworld.org/student_resources/powerpoint/levers/sld001.htm http://www.dynamicscience.com.au/tester/solutions/hydraulicus/humanbody.htm http://www.science-class.net/Anatomy/Support/Bones%20as%20levers.pdf Part of the body Type of Simple Machine Forearm 3rd class lever Legs 3rd class lever Head & Neck 1st class lever Foot (when walking) 2nd class lever Hand 3rdclass lever
There are 3 basic types of levers. 1st class, 2nd class and 3rd class. some change the direction of the force, some do not. some increase the force, some do not. A broom is an example of increasing speed, but not force. The direction of the effort (force you put in) and the resistance (force applied to the floor) is the same.
