3rd Class Lever 3rd Class Lever
Tweezers are an example of a third class lever.
I don't really know entirely why they are third class.
I thought they were first class?
fulcrum at on end. force applied in middle. resistence force at other end.
In levers of the third class, the fulcrum is at one end, the load (or object) is at the other and the force is applied in the middle. This is the configuration for tweezers.

They are both compound 3rd Class levers. The fulcrum is the bit which is stuck together, the Effort is where you press them to make them work, so in the middle, and the load is at the end of the tweezers/nail clippers where you make the magic happen :)
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 .
It is a first class lever
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.
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...)

Third class levers the Effort is between the Resistance and Fulcrum (FER) Examples are: · Mouse trap · Baseball bat · Tweezers · Nail clippers · Mandible · Hockey Stick · Fishing Rod · Door · Broom · Arm · Boat Paddle
A third and fourth hair-removal alternative: lazer removal and/or a pair of tweezers.
Scissors are first class levers. When you close the handle part then metal part closes cutting the paper.
There are three types of lever, with examples as follows: A seesaw (teetertotter) is a Class 1 lever A wheel barrow is a Class 2 lever A pair of scissors is a Class 3 lever
The noun 'tweezers' is a common, concrete, uncountable noun. The noun tweezers is a form of uncountable noun called a binary noun, a word for something made up of two parts to make a whole. Binary nouns have no singular form; binary nous are a short form for 'a pair of'. Examples are one tweezers or two tweezers and one pair of tweezers or two pairs of tweezers.

A class three lever is where the load is one side of the force and the fulcrum is on the other side of the force. An example is a pair of tweezers. Another example is the secondary lever in a pair of fingernail clips, i.e. the part that closes on the fingernail. (The first lever in a pair of fingernail clips, i.e. the part that you press on, is an example of a second class lever.)
