Is a light switch a 2nd class lever?
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.

second class lever
Can a lever be more than one class?
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.
Why is a third class lever useful for some tasks?

What type of simple machine are your legs?
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

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 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..

What are some examples of a third class lever slide show?
arm baseball bat broom ETC.
What are some examples of a first class lever?
A first-class lever is one in which the fulcrum is located in the center, with load and applied force on either side.Relatively common examples of first-class levers are:seesawcrowbarscissorsan oar attached to a boata hammer removing a nailfishing rodpliersHere are some good Examples, Crowbar's, Scissors and even Seesaw's!
Is a light switch a first class lever?
Yes, because the fulcrum is in the middle (the part that makes the switch go up and down) the effort is where you push up and down with your fingers the load is your fingers. It is a first class lever.
What are 5 examples each of first class second class and third class levers?
That's a tall order. I may need a lever to get up that high. For all the tools I will mention, some of them from a lever when you hold onto them and use them, others are levers in themselves. Let's have some fun, so here we go. First Class levers are like a teeter-totter or see-saw, a pair of scissors - which is two 1st class levers together, but I'll count as just one. There is also one in your elbow, one in your ankle, and another one in your jaw. That makes five. Second Class levers can be found in wheelbarrows, nutcrackers, your jaw and ankle, and vise grips; that's five again. Let's make it six with a canoe paddle, it's also a second class lever when you paddle with it in water. The last one is the easiest: Third Class levers can be found in lots more places, they are much more common. Here's a short, but diverse list: broom, fishing pole, hammer, your knee, pen, pencil, the joints in your fingers and toes not counting the first knuckle, a tennis racket, oh shucks just about every sporting device that you swing is a 3rd class lever when in use. The gas peddle in your car. Chopsticks, wooden spoons, fork, knife, spoon, toothbrush. And there are a whole lot more of all three.
