Question

Name the simple machine used for stapling a pin.

Answer 1

1. A stapler is a combination of two simple machines namely a lever and wedge.
2. During stapling a paper, the effort applied on the handle or lever of the stapler gets transmitted to the wedge of the stapler.
3. The wedge of the stapler forces the pin to staple through the paper.

Hence, the simple machine (combination of two simple machines to be precise) used for stapling a pin is a stapler.
