Is a nutcracker a first 2nd or 3rd class lever?

Answer 1

A lever that has the load between the fulcrum and the effort is known as a

second order lever.

Once again, the further away the effort is from the fulcrum and the load the greater the mechanical advantage of the lever.

Answer 2

In case of simple machine we have three quantities. They are power, load and fulcrum

Now there are three chances. Any one can lie in between the other two

Fulcrum is in the mid just as in case of scissor

Power is in the mid as in the case of forceps

Load is in the mid as in the case of nutcracker

Human brain may differentiate these three by allotting numbers as first, second and third. It is purely accidental. So the order is not so important. But the science behind is much more important. I am not sure whether it is second or third order. But I am sure it is not first order. So as per your query it has to be second order.

Answer 3

One that has two rods connected at one end that is used in one hand is definitely a third class lever.

Answer 4

1st class

Answer 5

2nd class

Answer 6

yes
