hello to all, would you recommend me a good book on which to study how you owe the examination of constructions of machines? I have juvinall and johns but I see that shigley is very used. My exam program is as follows:

' Threaded links and screws of maneuver. resistance of fatigue connections.
' conical couplings with friction and with sticks and tabs. grooved couplings
and other sewing and joint systems.
Metal and elastomeric elastic organs: traction springs and compression. springs
crossbow and spiral bending. Straight axis torque springs and cylindrical propeller.
' calculation, choice and assembly of bearings with swivel bearings and
Rolling. verification of possible deformations in mechanical shafts.
Nods on hertz theory. surface contact phenomena (corrosion, friction and
wear).
' design and calculation of cylindrical gears (right and helical teeth).
design of conical dense wheels. Endless helicoidal screw.
' brakes and clutches: typology, functionality and design.
'motor transmission: systems with straps, chains and gears.
Nods for calculating pressure vessels and design and verification of
forced connections

where to learn these topics rigorously?
Thank you.
 
I studied on juvinal-marshek and niemann/winter, but I also use johns as a consultation text.
the setting is different, but they are all three great.
I don't know shigley, but they speak very well.

Hi.
I used shigley even though everyone speaks very well of juvinall.

I've found myself pretty good, but if you already have juvinall, I'll shock you.
 
the indicated texts are all good! but if you want advice to pass the exam don't lose yourself in those booklets there because they are oceans of stuff, use them only from consultation but study on the notes of prof. then for the written only e.g. done and away, it is much faster to prepare!

Well, if the exam is also oral, (as was mine) studying on the book is absolutely indispensable. Of course you have to focus on the topics explained in lesson or still present in the program. no machine construction course manages to deal with all the johns (to say a name), but still some theory serves, not enough exercises.

I speak for my experience, I had a prof explaining the theory was a dragon and providing flakes. no one in progress from me prepared the examination on the books (no written or oral) and traveled on the 25-30 average!!! We were also good guys though:
 
in my university experience I studied all subjects on manyisms books taking a certain topic on one side and another topic on the other... .
That's because I noticed that maybe an author is more prepared on a topic, so he can explain it in a more understandable way while some other author treats it in an almost incomprehensible way. ...
in your case if you can study books in English I could suggest many others including popov (mechanical design)

Lucky. Unfortunately of prof good at explaining and providing dispenses, I had only 5 or 6 (on about fifty examinations).
often it was indepensable to integrate and try to understand the topics with the book.

I admit I've been lucky enough, because I think I've generally had good professors, I graduated from Ferrara. but if not so, what useful would he follow the courses?!? I also happened to myself that I had profes that when they explained there was no caxxo (just for the truth :smile:), there the first thing to do to save time is not to go to lesson. I follow a course only if I consider it indispensable to learn first and to save time. if I had to follow a course where the prof to explain is a dog and I already take for granted that to pass the tests I dovo "lost" (it is done to say :rolleyes:) in a shigley, rather than in a john etc... I'm going home and I'm going to do my own thing on the show. up to 1/2 receptions to better refine your knowledge and hello. the "following" a course is (or at least should be) a big added value for students in terms of quality of training and time spent for preparation, not a simple formality, because they are paid for that. the quality of this service is measured in this way by the appreciation of students. to us at the end of each course they gave us an anonymous test to do, precisely to test the quality offered by the teaching, but not only!!! also to give an evaluation on classrooms, libraries, lesson times, exam mode, teacher availability for clarification requests, receptions etc. Guys, we're paying, we have to decide and assess how things have to go. The time of the baron university must end. if things continue to worsen with the decrease of resources at university and teaching where we will send our children to study?! in germany? in Switzerland?

perfect! Yellow or white pages? :biggrin:

I tried!

I'm freaking out with the elem exam. construction of machines:

As you understand, my answer was because your question wasn't very "legal." :smile:

I'm sorry, did the prof not give you any supplies to follow? and the textbook?

p.s: If you have not submitted, I invite you to do so in the appropriate section.

in fact I said "if not.":biggrin:...I had not personally checked in the area ot.

from the request he made in his first post (material covered by copyright) I thought he had not read the regulation.
 
Of course, I'm sorry for stupidity. I showed up on 2 pages, but I'm not sure it was good!
For the rest...
Not even talking about it. textbooks: juvinall, shigley, industrial technical design, mechanical construction design, machine design. all accompanied by front lesson notes of course!
The disaster lies in the fact that, despite having a detailed and satisfactory theoretical preparation, the examination always hides puzzles.
I'll explain.
Suppose we have a structured task with 20 type exercises:
1-study a beam with central load 3 times hyperstatic and dimension the screws on the flange etc. etc.
2- dimensional welding of a flange that supports a tensile load, bending, twisting... 3-size bearings for a reducer with data, etc. etc. ...and so on....
In such an examination I would take the "nobel" to understand.

Here, instead, it is a question of reading the exam proposal (on 3 hours, I pass almost 1 to understand what it is!), to understand how it works, to intuit the hippo (always present!), then to make the calculations! on 4 appeals I arrived at 14/30 as a maximum result which is rather frustrating (16/30 is the least to be able to try the oral, but it is obvious that perhaps it is better to remake the writing!).

not knowing where to crash my head I took a ride on the web to understand how they treat the exam in other locations and I had the clear impression that it is quite different! :

now I quarrel with this type of examination: a hydraulic jack to be sized for a test of sinking graves!

Patientia docet!
 
If really the exam mode is this I would say that the number of people who pass it is close to zero.

Honestly, I don't know what to say to you... I did the exam like this:
- two "body" exercises in 2 hours;
- compulsory oral of about 1.5 hours minimum for all votes from 15/30 onwards.


the science examination of the buildings instead was only oral and lasted 3.5 hours (they made you exercise a hyperstatic structure and then asked you theory).
