How Can I Solve an Electrical Machine Theory Problem Without a Solutions Manual?

Homework Statement

So I'm working on question five from my book.

The book references a earlier problem, which you'll find below for further reviewing purposes.

The Attempt at a Solution

I apologize for posting the question as a picture. But given my situation, it is best. If you have difficulty reading it let me know.

Alright so I'm starting to panic here a bit. The questions is from An introduction to Electrical Machines and Transformers Second Edition by George McPherson and Robert D. Laramore. I feel a bit lost in the class. The prerequisite for the class was electric magnetic field theory. I didn't take generalized machine theory in my undergraduate, which would have been useful for this class. It was a requirement for my undergraduate.

Anyways. I have attempted to find the solutions manual for this book. The book was published 25 years ago. Searches for most of the problems from the book lead to nothing in Google. It appears that the solutions manual was never published neither. So finding the solution and attempting to understand the solution is out of the question it would seem.

Now that, that option is out of the way, the only way I can solve this problem is to understand the material and with assistance from others. Looking through my class notes, I can't even find del_FR or del_SR or beta or |R|. So my class notes are of no use to me.

The chapter from which the problems is over 100 pages long. I have found some of these symbols in the chapter and have read the sections but it's of no help in solving the problem.

Any help on how to solve this problem would be greatly appreciated thanks.

Hello there,

I understand your frustration and feeling lost in the class. It can be overwhelming when the prerequisite material is not fully covered or understood. However, don't panic, there are always ways to learn and understand the material.

First, I would recommend reaching out to your professor or classmates for help. They may have a better understanding of the material or may be able to provide additional resources or explanations.

Secondly, I would suggest looking for online resources such as videos or tutorials that explain the concepts and equations you are struggling with. There are many online platforms such as Khan Academy, Coursera, and YouTube that offer free educational materials on various topics.

Also, try breaking down the problem into smaller parts and tackling them one at a time. This can help in understanding the overall problem better.

Lastly, don't hesitate to ask for help from other scientists or professionals in the field. You can also try reaching out to the authors of the book for clarification or additional resources.

I hope this helps and good luck with your studies!
