Need help with two physical science questions

Question

I’m taking notes with the whole remote learning thing being new I’m still adjusting and wanted to ask if anyone has the answers to these so I can use as notes.

1) what is the relationship between mass and distance in a first class lever.

2) what is the relationship to mass and distance on each side of the first class lever when each side is in balance?

Answer 1

Let me give it a shot.

For 1) it strongly appears that your going over torque: r x F , thus the further the distance (r) the greater amount of torque can be generated. Conversely, it takes less force for rotation the greater the distance. In basic terms the longer the wrench the easier it is to turn the nut on a bolt.

2) I think answer they may be looking for is that because the lever is balanced the distance doesn't matter because the center of balance comes to a single point.
