So these days I have been working through the problems contained in the book Introduction to classical mechanics by D. Morins. I will say I really liked the problems. Apart from some problems with solutions, the book contains over 350 exercise problems with no solutions. So I was thinking we could make a solution manual for the book.
Facts about the book
The problems in the book, have different stars labeled on them;
The problems are excellent, and have the Brilliant.org feel to them. I was hoping that every week, I will post a couple of the problems, and after gathering ideas and solutions, One solution will be selected (maybe more if they have different approaches), for that particular problem. In a sense it would be a Brilliant.org solution manual.
Please comment below, if you agree with the idea.
Mardokay has shared a link to the book.
And I have worked my way through some of the book, and if you have ideas not clear I would be happy to help.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

I think it is a good idea, by the way it is a good book thanks for sharing. I found an online pdf format of this book yay we don't have to buy it Introduction to classical mechanics.I will re-share this.

T, then it is evident that :
If the tension in the string is2Tsinθ=λ(fl)g
As you mentioned, the tension will be different from the friction...That is true..Considering the forces for the part of the rope which is in contact with the incline,
F=21−fmgsinθ+T
And we know that, the friction force F is simply μN=1⋅21−fmgcosθ.
From these equations, we get,
f=cosθsinθ+cos2θcosθsinθ−sin2θ
And, we can find the maximum value for this function easily..Is this correct?

8π as @Mardokay Mosazghi mentioned in the note with the question, right?
Yeah, I think this is correct. The maximum value is attained atLog in to reply
pi/4 as @Anish Puthuraya said @Sudeep Salgia
Wait that it right, i was convinced that it wasLog in to reply

4π
I think he meant to say that he was convinced that my original solution was correct, and that the answer wasLog in to reply

@Anish Puthuraya will keep a lot solutions ready by then, making your work easier. :D

Hey thanks for the link. BTW, can you give the E&M by david morin too?
Log in to reply
Sorry @Kartik Sharma there is no pdf for that one i searched and searched but couldnot find it,try it and tell me
Let's do it

Great lets just wait a couple of days, for people to see this, and start.
It really sounds interesting. I would love to join in.

Same here : )
Glad you think so, i have included some of the statics problem, as a sample, check it out here
This is not going to be the real thing.
Me too
How many per week, would you guys say is optimal?

Personaly I am here everyday so the planning goes for others
hey
Good idea. I will try to help.
Good idea.........
