What are 5 examples each of first class second class and third class levers?

Answer 1

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.
