Hi All,

I am doing a problem on mechanics and find that the answers are not matching (mine are coming .0085 and .002 inch).I am attaching the question and the answer herewith.

I presume that bending effect is not to be taken into consideration as otherwise the dimensions of the beam would have been furnished.I tried both direct stiffness and virtual work methods and didn't get the required answer.

Can anybody validate the same.I restrain myself using FEA analysis fo it as it would have taken thet bending effect also.

Thanks and Best Regards

The abstract of the paper is as follows (to appear in International Journal of Mechanical Engineering Education)

 A dynamic force-field analogy for analyzing organizational change is presented. Instead of

just analyzing the driving and restraining forces in the traditional force-field analysis, which is similar to

the static analysis in solid mechanics, the forces opposing change can be modeled in terms of viscous

or frictional forces that may be encountered. Some analogies between organizational change and the

Somebody have the Michell's work about structural optimization??: The limits of economy of material in frame-structures. Please. I need it....if you can send it to me...please contact me. Thanks

hello,



 
I am a mechanic eng. M.S student with interest on material science-energy-applied mechanic and the fields like this. 







could anyone tell me what are the recent projects are doning in fuel cell field? are the people doing structural mechanical research on fuel cells and etc?







as projcet going to be done at 2011 what are the newest topics?

Professors Mike Adams and Walter Herzog are the latest speakers to be announced, joining Professors Alfons Fisher and Greg Sawyer as key speakers during ICoBT 2011. For more information, go to http://www.biotribologyconference.com/speakers.asp

 Dear all,

I am doing a fracture analysis of composite beam using ANSYS please let me know about the type of elemnt that i should use for meshing?

thanks in advance
