Finite Element Section[edit]

The section at the end of the article for finite element seems like it could use some help. Is "MSC MARC MENTAT" really notable software? I'm familiar with both ABAQUS (which was spelled incorrectly before the edit) and ANSYS, but have not heard of this software mentioned. Perhaps we should keep that statement to mainstream software? Should we also mention open source or free alternatives? Finally, the last sentence seems to suggest that heat and fluid flow problems cannot be solved using FEM, but instead require FDM and FVM. I'm not convinced this is the case - but rather FDM is a separate method of solving similar problems. Tevonic (talk) 20:10, 11 January 2009 (UTC)

I changed Marc to Nastran, which is far more common. The section is only listing common codes. FDM and FVM are mentioned with thermofluids uses, not structural. -Fnlayson (talk) 20:54, 11 January 2009 (UTC)

Maintenance[edit]

I don't see much mention on Wikipedia about the role of maintenance. I thought I would find more here. Am I just not finding the info that is out there? 70.250.176.80 (talk) 00:56, 7 March 2009 (UTC)

you are right. more inoformation needs to be put about the huge role of mechanical engineers in maintenance of various systems.Mecha19 (talk) 11:41, 1 July 2009 (UTC)

Introduction[edit]

hi fnlayson, i think the intro is alright now.

its not complicated and is right to the point.Mecha19 (talk) 16:53, 26 August 2009 (UTC)

You're still missing the point and did not bother to read the Notes above. Discuss on the article talk page as it say. -Fnlayson (talk) 16:55, 26 August 2009 (UTC)

fnlayson i dont know where the notes are?

sorry but i think that the revert before in terms of physics and chemistry was ok but now the current edit that you made is a bit weird :(

the intro is really simple. i searched for your discussion but could not find it. could we discuss it over here.

the intro is really simple actually.

let me know what you think about it :) Mecha19 (talk) 17:30, 26 August 2009 (UTC)

im not quite sure why u removed materials science from the list?
im explaining in a nutshell what mechanical engineering is about, which is physics+materials science.Mecha19 (talk) 17:55, 26 August 2009 (UTC)
You don't seem to get what it is trying to say. The basic principles Mechanical Engineering was based on is stated in the 1st paragraph. The core concepts in ME used today are listed in the 2nd paragraph. -Fnlayson (talk) 19:43, 26 August 2009 (UTC)

yea i got that fnlayson, i wanted the intro to show that the basic principles of mechanical engineering are physics and materials science. i want the intro to zoom in on what mechanical engineering is all about in just a few sentences.Mecha19 (talk) 07:33, 27 August 2009 (UTC)

importance of mechanical engineer in construction

I believe the introduction could be improved greatly.

  • The first citation is Reference.com's definition of "mechanical"... not even "mechanical engineering"
  • If we are going to use Reference.com, we might as well use it for the first sentence of the entire page: " Mechanical Engineering is the branch of engineering that enables design, production and operation of machinery and tools. " Fractal618 (talk) 03:19, 27 July 2014 (UTC)

Edits Made[edit]

I just made 3 fairly minor edits. First, I thought the description of Mechanical Engineering in intro para was a little vague ("Mechanical engineering involves the analysis, design, manufacturing, and maintenance of various systems"). So I added an alternate definition that I think is more complete (in my opinion at least). Second, there was a statement that Mechanical Engineers are "happy workers according to national statistics" with no citation provided. This does not sound like something that belongs in a serious article so I deleted it. If the original author strongly feels it should go back I believe it really needs some kind of reverence or citation to substantiate it at least. Third, "Mechanical engineering students usually hold one or more internships while studying, though this is not typically mandated by the university." is not exactly accurate, so I reworded to say this is common in the USA (as opposed to "usual" which implies it is more universal, which may not be true in all countries or even necessarily in the USA). Hope none of this ticks anyone off. Trying to improve. Turbine1 (talk) 06:22, 3 January 2010 (UTC)

The "According to the American Heritage Dictionary" sentence needs a proper inline reference. I thought the sentence was fine or better before though. -Fnlayson (talk) 00:03, 4 January 2010 (UTC)
Feel free to revert or re-edit if you think you have better wording. My opinion, "various systems" was a little too vague and all-encompassing and could mean a lot of things outside of the realm of Mech Engrg (electrical systems, computer systems, etc.). Mechanical Engineering, I would say, is specifically about Machinery, in other words systems involved in the generation and transmission of energy in the form of heat or mechanical work. Anyway, don't want to tie up anyone with a lot of wordsmithing. No offence taken if you revert or change this. If nobody wants to change it I will come back and insert the inline reference. Turbine1 (talk) 23:57, 4 January 2010 (UTC)
The current version is fine. I was just accustomed to what was there before. -Fnlayson (talk) 00:04, 5 January 2010 (UTC)
I rewrote the intro section to try to fit more with WP:LEAD, where the intro should both introduce the topic and cover the major points. I reverted the first sentence to talk about 'mechanical systems' - since this is mechanical engineering, it seemed to make good sense to tie it in with machines. Also added a reference for the inline citation. Âme Errante (talk) 06:53, 9 May 2010 (UTC)
That's good. But rewriting and removing text are not minor edits and should not be marked so. -Fnlayson (talk) 08:33, 9 May 2010 (UTC)

Muje mechanical eng ke admission ke bare main information chahye...........! —Preceding unsigned comment added by 110.36.53.226 (talk) 17:16, 12 May 2010 (UTC)

Related Fields[edit]

Mechanical Engineering grouped with many engineering disciplines such as aerospace engineering, astronautical engineering, power engineering, chemical engineering, and manufacturing engineering. There are only slightly few credits difference. Even applied mathematics sometimes grouped with Mech. Eng. Does someone know what is the main focus of Mechanical engineering? For example nuclear engineering deals with nuclear power, chemical engineering deals with chemical sciences, electrical engineering deals with electronics and defence systems? What is the main focus of mechanical engineering??

Coursework[edit]

I don't know much about Mechanical Engineering, but I was almost positive that the theoretical foundations are found in physics. Why isn't physics listed under coursework? Don't all Mechanical Engineering students take basic physics in addition to the more specialized studies of statics et. al? —Preceding unsigned comment added by 65.50.39.118 (talk) 04:34, 7 September 2010 (UTC)

Physics, Chemistry and other prerequisite classes are generally taken in the first 2-3 years of college. Physics, and Chemistry are mentioned in the text, but there's too many classes to list pre-engineering classes with the engineering ones. The list is long enough already. -fnlayson (talk) 12:52, 7 September 2010 (UTC)

levelling during machine erection[edit]

what are the basic things to be noticed before the start of erection of a machine —Preceding unsigned comment added by 123.201.190.175 (talk) 07:49, 7 March 2011 (UTC)

This question is related to what? --THE FOUNDERS INTENT PRAISE 12:28, 7 March 2011 (UTC)

Kinematics and dynamics[edit]

Kinematics and dynamics are both branches of mechanics. So why have a separate sub-heading for kinematics only. I think instead of having a separate sub-heading, it should only be mentioned in mechanics as a part of the list, only. Priybrat (talk) 15:48, 5 August 2011 (UTC)

No, Kinematics is an advanced form of dynamics. It is covered in class(s) after dynamics. -Fnlayson (talk) 15:54, 5 August 2011 (UTC)
They are both considered branch's of mechanics and not each other. I studied dynamics first. Dynamics, is motion of bodies under the action of forces and Kinematics is motion of objects without reference to the forces. I do agree that kinematics is more complex and a celebrated research field but still it remains a branch of mechanics. Otherwise Fluid mechanics should also be given a separate heading. Priybrat (talk) 16:06, 5 August 2011 (UTC)
Isn't this basically due to the fact that these subjects have their own article, and it's an attempt to list them. --THE FOUNDERS INTENT PRAISE 16:43, 5 August 2011 (UTC)
That's what I am saying, Kinematics should a part of the list under heading mechanics. Kinematics also has a separate article. So, there's no need to have a large explation for it in this article. Priybrat (talk) 17:05, 5 August 2011 (UTC)
I was just trying to figure out why things were listed like they are. --THE FOUNDERS INTENT PRAISE 22:35, 5 August 2011 (UTC)
So, whats your say on this ? Do you think the list need to be changed? In the course work section it's written that "Mechanism design (including kinematics and dynamics)" Priybrat (talk) 15:57, 6 August 2011 (UTC)
  • Kinematics text summarized and moved to Mechanics section. Adjust the Kinematics entry wording if needed. -Fnlayson (talk) 16:39, 25 August 2011 (UTC)
