The solution to problem 21 in Chapter 3 in Classical Mechanics by John Taylor is messy and slightly incorrect. I believe that I have a clearer solution to the problem, and I want to know how to submit an alternate solution for the problem on this website. What are the steps to follow in order to submit an alternate solution?

Particles of mud are thrown from the rim of a rolling wheel. Ifthe forward speed of the wheel is v₀,and the radius of the wheel is b, show that the greatest heightabove teh ground that the mud can go is

b+(vo^2)/(2g)+(gb^2)/(2vo^2)

at what point on the rolling wheel does this mud leave?

(note: It is necessary to assume that vo^2 â¥ bg.)

This is a question from the book "Analytical Mechanics" seventhedition by fowles and cassiday. chapter 4 problem 7. cramster "has"the solution worked out but two problems. 1) it's wrong and 2) itis damn near impossible for me to follow.

The person doing the problem just pulls random equations out touse without saying why. If i knew why they were being used thatwould basically solve most of my problems about the question. Alsothe few discriptions the problem has seems to have very badgrammar/punctuation and so trying to follow it is nearimpossible.

So any work through of the problem would be great. But more ofwhat I'm looking for is what should be going through one's mindwhen proceeding with the problem? What equations should be used andWHY?

Chapter 21, Problem 51

Consult Interactive Solution 21.51 to see how this problem can besolved. A coil rotating perpendicularly to a uniform magnetic fieldcontains 390 turns and has an area per turn of 2.5 x 10-3 m2. Themagnetic field is 0.093 T, and the current in the coil is 0.12 A. Abrake shoe is pressed perpendicularly against the shaft to keep thecoil from turning. The coefficient of static friction between theshaft and the brake shoe is 0.56. The radius of the shaft is 0.011m. What is the magnitude of the minimum normal force that the brakeshoe exerts on the shaft?
