Finding Equations for Simple Structural Mechanics Problems

Click For Summary

Discussion Overview

The discussion revolves around finding specific equations related to simple structural mechanics problems, particularly focusing on beam support scenarios. Participants seek fundamental equations for various loading conditions on beams, referencing common engineering handbooks and resources.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant, LarryR, requests equations for beams under different loading conditions, including simply supported beams and cantilever beams with various load placements.
  • Another participant mentions the EIT handbook as a source for the requested equations.
  • A different participant recommends "Roak's Formulas for Stress & Strain" as a comprehensive handbook for beam equations.
  • There is a suggestion to check the NCEES website for downloadable resources related to the EIT handbook.
  • Links to additional threads and resources are provided for further exploration of the topic.
  • One participant expresses a desire for a layman's explanation of how the formulas were derived, indicating a need for simplified understanding.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of specific handbooks and resources for finding the equations, but there is no consensus on a single source or method for accessing the information. The discussion remains open with various suggestions and requests for clarification.

Contextual Notes

Some participants express frustration with the difficulty of finding straightforward equations online, indicating potential limitations in accessibility or clarity of available resources.

Who May Find This Useful

This discussion may be useful for individuals seeking fundamental equations in structural mechanics, particularly those returning to the field after a long absence or those looking for accessible resources.

I'm out of college for decades, and all my "handbooks" and college books have been packed away and inaccessible for some months.

I need a source, or the equations as follows [all very simple, fundamental stuff; Chap One in "Strength of Materials", so to speak]

1] Beam supported both ends, with W downward force NOT NECESSARILY in the center.
2) Cantilever beam; rigidly affixed to one end, with W downward force at some location.
3] Same as one, but with uniformly distributed load
4] Same as two, but with uniformly distributed load.

When I do searches on the internet, I get thousands, but all in reports, or something; I just need the equations; yes, you may email me if you prefer.

Thank you very much.

"Roak's Formulas for Stess & Strain" is a good handbook with every equation for beams I can think of in it. Ton's of equations in it.

Are there more pages available?

Available to be "seen". Do YOU have to download ea page, for example as you did in THIS response? The internet is SO big, yet I cannot find the simplest equations as in a textbook.

I DO thank you for your efforts; I was beginning to give up; I've got to dig out [from SOMEWHERE] my old "Strength of Materials" book and Schaum's Outline for same.

Try this :
 
try this: http://www.aps.anl.gov/asd/me/Calculators/ElasticBeam2.html
 
If you may need some similar information again try:

"Mark's Standard Handbook for Mechanical Engineers"

I believe it is on the 10th edition now.
 
can anyone explain how the formulas where derived - unmathematically. AKA. layman's terms?
