reducer with conical toothed wheels

[toyo10]

Hello again to all!

I should play part b of this text (http://dmmf.mec.uniroma2.it/docs/dm1_2013/0708es2013.pdf), I have done a draft of the exercise and would like to know whether they are on the good road, or whether to make and where valuable corrections.
I have not yet finished doing the other exercise but I had to commit myself already in this, so also my other question remains open!
in many at my university course follow these posts and we look forward to understanding more about these exercises in view of the exam!
Thank you again!

identical exercise already discussed and reviewed on this forum. go look for it and you will find all the directions. at first glance it seems correct. However it is "standard" stuff

I put some notes on your drawing. However these exercises that for 2 years to this part are posted on the forum are always the usual, so first check the available material.
