AI Thread Summary
Pulling lace B quickly results in it tearing, while pulling lace A slowly leads to its tearing. The discussion emphasizes the need to understand the underlying physics, particularly Newton's laws and the elasticity of strings. Participants stress that users must demonstrate their attempts at solving the problem to receive assistance. The forum rules require showing relevant equations and efforts before help can be provided. Engaging with the problem is essential for meaningful support in understanding the differences in outcomes.

Sorry, can you reword this using proper English as it is very difficult to understand what you are asking.

Also, please show your attempt at a solution.

I think he's trying to say that if you pull the end of the string fast string B will be torn while if you pull the string slow, string A will be torn

maybe..

That is exactly how I read it.

msitworld: as stated above, you must show an attempt to answer 'why' this is the case. It is not an easy task to do so, but you have to start somewhere, in consideration of Newton's laws and the fact that strings are not rigid; they stretch. Give it a try, and perhaps someone will help. Welcome to PF!
 
yes acuben
if you pull the string B fast it will be torn while if you pull it slow, the string A will be tornwhy Why this happens ? what is the Difference between first and second mode results ?
 
msitworld, you must show an attempt to answer this, not just demand an answer.

Otherwise you won't get any help.

what help ?
 
You want help answering the question.

We can only assist you in getting to the answer, we can't give you the answer.

You must show an attempt before anyone can help you get to the answer.

When you posted your problem, the template that shows up clearly indicates that you must list your relevant equations and show an attempt at a solution before you can receive assistance with your problem. Once you do, I'm sure someone would be glad to assist in this not so easy to understand problem. These are forum rules. If it's just an answer you are looking for, you should ask your question on another website. Thank you for your understanding.
