Mechanical engineering was a Engineering and technology good articles nominee, but did not meet the good article criteria at the time. There may be suggestions below for improving the article. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

Introduction

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)[reply]

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)[reply]

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)[reply]

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)[reply]

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)[reply]

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)[reply]

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)[reply]

I believe that this sentence is not neutral: "He is also considered to be the inventor of such mechanical devices which now form the very basic of mechanisms, such as the crankshaft and camshaft." I am considering editing to make it more clear that this is an opinion associated with a source.Cole2R (talk) 19:23, 4 September 2018 (UTC)[reply]

The word "considered" implies an opinion such as a general consensus of sources, though you may be referring to something else in that sentence. -Fnlayson (talk) 19:51, 4 September 2018 (UTC)[reply]

Spot on to what I was referring to. Wasn't sure if the sentence is considered neutral. Recommend revising to: "Al-Jazari is also the first known person to create devices such as the crankshaft and camshaft, which now form the basics of many mechanisms."Cole2R (talk) 19:55, 4 September 2018 (UTC)[reply]

Areas of Research

FEA - Very little description on what FEA solves for other than "structural analysis". More description about the specific goals of these methods can be added. (deflection of solid body, different types of stresses). Additionally, there is very little mention of how these meshes are used. Perhaps adding information about convergence of analysis leading to certainty, since too small of a mesh may not result in results that model a part or system in the real world.Cole2R (talk) 20:16, 4 September 2018 (UTC)[reply]

Suggested addition for an introduction sentence: "Finite Element Analysis is a computational tool used to estimate stress, strain, and deflection of solid bodies. It uses a mesh setup with user-defined sizes to measure physical quantities at a node. The more nodes there are, the higher the precision."Cole2R (talk) 20:38, 4 September 2018 (UTC)[reply]

Biomechanics - I believe some information should be added to the biomechanics section to talk about not just using mechanics in the biological field, but reverse engineering nature. There is a lot of research currently underway on the properties of spider webs and bone matter. Both are considerably stronger (found in nature) then current human made counterparts. For example, Bone Mass is over 5 times as strong as steel per unit of weight when dealing with compressive stress, while being slightly stronger in terms of tensile stress.Cole2R (talk) 19:17, 4 September 2018 (UTC)[reply]

What does everyone think about adding something like this to biomechanics section?: "In the past decade, reverse engineering of materials found in nature such as bone matter has gained funding in academia. The structure of bone matter is optimized for its purpose of bearing a large amount of compressive stress per unit weight. The goal is to replace crude steel with bio-material for structural design." — Preceding unsigned comment added by Cole2R (talk • contribs) 20:21, 4 September 2018 (UTC)[reply]

Mechatronics - This section was just adjusted slightly by me. Previous information was inaccurate. More information could/should be added about the sensors that can be used to implement mechatronic concepts. Examples include: Thermocouples, pressure transducers, digital multimeters, waveform generators for testing, etc. — Preceding unsigned comment added by Cole2R (talk • contribs) 02:10, 9 September 2018 (UTC)[reply]

1845 look it up

gg 156.146.138.183 (talk) 00:10, 16 December 2023 (UTC)[reply]

And? That year is not mentioned anywhere in the article. See WP:TALK#COMMUNICATE. -Fnlayson (talk) 01:12, 16 December 2023 (UTC)[reply]

Picture in the lead

Why is an ENIAC computer used to illustrate this topic? ENIAC was used for much more computationally intensive tasks than the mechanical design of the time. Some simple analog devices would be a better symbol if the 1950s is what we are about. Викидим (talk) 02:48, 30 January 2024 (UTC)[reply]

No idea really. An IP user added that recently. Now is a good time to remove it (thanks for reminder). -Fnlayson (talk) 02:52, 30 January 2024 (UTC)[reply]
