# Atwood Machine: Reduce Exp Errors By Stabilizing Masses

• wiccabean21
In summary, when conducting experiments using an Atwood Machine, tying a string that is equal in length to the string connecting the pulley to the bottoms of the two masses can help to reduce experimental errors. This is because it helps to stabilize the masses and ensure that they travel the exact same distance, contributing to more accurate results. However, it is important to note that this does not refer to mechanical stabilization, but rather mitigating imperfections in the construction of an ideal Atwood Machine.

## Homework Statement

String that is equal in length to the string connecting the pulley is sometimes tied to the bottoms of the two masses, where it hangs suspended between them. Explain why this would reduce experimental errors.

## The Attempt at a Solution

I'm not sure but does the string help stabalize the masses when one is dropped so they travel the exact same distance?

The question asks why it helps to reduce experimental errors. It's not referring to mechanically stabilizing anything.

What are the assumptions for an ideal Atwood Machine? What keeps you from being able to build an ideal/perfect AM? What could you do to mitigate these imperfections?

But I don't understand what the experimental errors are... how could string have affected it in any way?

Did you read the link that I posted? The clues are in there. (Or in your textbook's description of the AM)
