Discussion Overview

The discussion revolves around the compilation of essential equations for Mechanical Engineering lab work. Participants explore the utility of such a list, the importance of understanding underlying theories, and the context in which these equations are applied.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant seeks assistance in building a list of formulas and equations for Mechanical Engineering students in lab work.
  • Another participant argues that merely compiling equations is insufficient without understanding the theory, assumptions, and applications behind them.
  • A question is raised about which specific lab or area of study is being referenced, noting the vast number of equations in the field.
  • A participant mentions their website aimed at providing physical equations for software development, requesting useful formulas from areas like fluid mechanics and dynamics.
  • Some participants suggest that consulting textbooks could eliminate ambiguity in the equations.
  • There is a request for suggestions of the toughest equations, with a specific mention of the Navier-Stokes Equations as an example of complexity.
  • Concerns are expressed about the practicality of listing complex equations, with suggestions that simpler, more relevant equations might be more beneficial.

Areas of Agreement / Disagreement

Participants do not reach a consensus; there are competing views on the value of compiling equations without context and the necessity of understanding the underlying principles.

Contextual Notes

Participants highlight the importance of context and relevance when selecting equations, indicating that some equations may require additional information or assumptions to be useful.

I am building an list of formula and equation for use by Mechanical Engineering students in their Lab work, can anyone help me to build the list.
 
Engineering news on Phys.org
Just compiling a list of equtions is useless. Students need to understand the theory behind the equations, assumptions made, and how they are used. By the time you do all of that, you've written an entire set of textbooks.
 
What lab specifically? There are literally thousands of equations we deal with.
 
I run a free online website where I have converted several formula and equations related to mechanical engineering, I want to add more, I see many students in the under developed nation use in their lab and would like to see more.

I am an software engineer, thus I need physical equation for formula as inputs, so I can convert into free wares.

Send me the most useful formulas and equations used in fluid mech, hydraulics, flow, dynamics, etc..
 
How about picking up a textbook, then there's no ambiguity?
 
i would like people to select the toughest ones kindly suggest

What good is that going to do you? OK. Here's a toughie...the Navier-Stokes Equations. Now what? If you look at any other website out there that does this for us, they have taken the time to amass information they feel is beneficial to engineers and students. You need your site to be useful, not just a place that lists equations.
 
I agree... what you are after is pointless. hahahaha Navier-Stokes (James shudders)

Sometimes a list of equations might be useful, but only if they are simple, perhaps like Newton's equations of motion. But if you we to get into things like the Colebrook-White formula for pipe friction losses that contain constants and variables that require other formulae to work out, it will be completely useless.

If you want a general list... keep it simple, and keep it relevant to what you are doing.
