Question

pens are class 3 lever - justify​

Answer 1

Pens are class-3 levers too: by pivoting them on our hands and holding them in the middle, we get much more control over the nib or ballpoin

Answer 2

$\mathfrak{\huge\underline{Answer:}}$

class 3 lever has the effort between the fulcrum and the load. Because the load and effort are on the same side, they move in the same direction. In a class 3 lever, the effort is always closer to the fulcrum than the load, so class 3 levers are used to make the load move faster.
