Mechanical Principals Assignment Question

Click For Summary
The discussion revolves around a mechanical principles assignment involving calculations of stress, strain, and changes in dimensions for a component under compressive force. The original poster seeks validation for their answers, which include several calculations that were critiqued for incorrect units and signs. Key points include confusion over the use of negative values for Young's modulus and Poisson's ratio, as well as issues with unit conversions and the precision of calculations. The conversation emphasizes the importance of attention to detail in engineering calculations and the need for clarity in unit usage. Overall, the poster expresses gratitude for the assistance received while acknowledging gaps in their understanding of the material.

I can't thank you enough for your help with all of this. This time last year I was just starting the course and I have had to learn everything from scratch. I hadnt touched algebra in 16 years and there was no explanation behind the reason why engineers use x10^3 as apposed to x1000. I have learned most of the methods I use by searching outside of the e learning and sifting through forums and youtube videos, Therefore there have been gaps in my education hence the reason I make mistakes alot.
I have a hundred questions I could ask you but I won't take up all of your time. Thanks again for your help!
Hello, by any chance do you have an answer to question 2 for this assessment?

I can see a question 1 and a question 3, but no question 2.

Yeah Q2 isn't on the thread I was just asking if he had completed the question I'm guessing so, as this thread is pretty old.

Yes I did complete question 2 but the whole point in this type of learning is find out the answer by making an attempt as apposed to asking if someone will give you the full answer for free. If you understand the subjects you are studying you will help yourself in future assignments when you come across similar questions.

If you could just jump off your high horse for a second, you seem to have miss understood me just like the person who was helping you out above. All I wanted to do was compare my answer for Q2 with a person who has taken the same question. Don't worry too much I submitted the assignment this afternoon sure I got the correct answer.

Forgive me for riding my high horse. But this does sound simply like you have asked me by any chance do I have an answer to question 2 for this assignment. Without you onces previously saying, I have made an attempt at this one can you offer any advice.

Well anyway good luck! I got a distinction for my efforts hopefully you will do too.
