Homework Help Overview

The discussion revolves around a problem in advanced mechanics, specifically focusing on the relationship between variables X1, X2, and delta r as presented in a diagram. The original poster expresses uncertainty about how to approach the problem.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to utilize the Pythagorean Theorem to relate X1 and X2 to delta r but is unsure of the initial steps. Another participant suggests using the theorem as a hint. A participant later questions the accuracy of their calculations after obtaining a numerical result.

Discussion Status

The discussion has seen some productive exchanges, with hints provided and attempts to clarify the problem. However, there is no explicit consensus on the correctness of the calculations, as one participant expresses doubt about their answer after submission.

Contextual Notes

There is mention of a specific homework platform (WebAssign) and the potential for errors in answer submission, indicating constraints related to the homework format and expectations.

I have this question for my WebAssign and I am not sure what to do with it. I thoght about how to use the X1 and X2 to get delta r but I really have no idea where to start. Please help! Much appreciated

Hint: Use the Pythagorean Theorem.
 
I used it and got 11,624.97312. I entered 11,624.97 into Webassign and it came out a wrong answer. Could someone tell me if this is the right answer and I am entering it wrong or if I completely did this wrong?

I found one leg of the small triangle at the top of the diagram by subtracting 4900-3200, and used X1 as the other leg..then uesd the pythagorean theorem.
 
nevermind, got the answer, thanks a lot. I've got another mechanics question if anyone's around.
