Hello everyone,

Mechanism To Increase Energy Efficiency.

Submitted by Jigar Y. Patel on Sat, 04/04/2009 - 06:49

View the figure attached. It is about using Cam for increase
energy efficiency. Cam are generally used to open and close valve of IC
Engine. I am going to show you another use. Left side initial position.
Right side final position. Redius of cam continuously decrease.Sliding
weight (MG) applied on Cam. With the help of rope weight(MG*Cos(b)) is
fixed with cam. We consider b as 45. So cos 45=.70. This fixed weight
should be 0.70 MG. Which balance the sliding weight applied on cam in
tengential direction. As sliding weight come down the fixed weight go
up. But the twist is the redius of cam decrease nominal continuously.
So sliding weight come down little bit and fixed weight go up much
more. We consider sliding weight come dowm H2 height and fixed weight

The above article is an April Fool's joke. It reminded me of the recent "discoveries" in the mechanics community regarding stress tensor.

this is Probal from university of western ontario (UWO). I am working on three roller flow forming process and i have to model the deformation specially in the splined area. could you please give me any idea or give any link so that i can have an idea what to do.

thank you probal

Molecular dynamic simulations for carbon nanotubes

Submitted by tkrish on Tue, 03/31/2009 - 04:19

When using molecular dynamics simulations to study the variation of buckling strain versus aspect ratio of SWCNTs, is it necessary to keep the strain rate constant or displacement rate constant? Kindly appreciate your comments.

Hi all

I am currently in my Master Degree in Civil Engineering at University of Michigan. I am doing a research on concrete wrapped CFRP sheets and I want to do Finite Element Analysis using ANSYS. I am not able to model concrete in ANSYS. Can anyone please help me out with that.

Awaiting the reply....

Thank you
