Engineering - May 2007

There is a science that can increase our performance by up to 4 to 1, can reduce and control failures by up to 1000 to 1 and save 70% of the costs. It does require some education but why is it not being used for our critical situations?

I know Chromium increases Yield strength, so do Carbon , Molybdenum, Vanadium and Nickel to some extent. But Chromium reduces ductility and toughness, which is the main criterior for selecting it for any apllication. Chromium also reduces stability of austenite in as-qunched coditon and favours carbide formation. So why it is such a popular addition to Hadfield steel.

Doing a school project for can crusher.

I have the linkage to the jaw figured out.

PROBLEM:

I want the back part of the base (like tongue) to flick the flattened can out of the "mouth" on a return stroke. I can't think of a way to bypass the "tongue" on a down stroke. I've been pulling my hair out for a week. I can't use gears in this system cams are ok.

Thank you for any help.

The engineering design world has evolved so much that the pace at which technology is moving shows that within a split second, myriads of new, efficient and well structured designs which help to improve upon human existence are either discovered or produced in such a way that the whole human community cannot help but apppreciate the very essence of her existence. People can pay their way through for a vacation to the moon. These tremendeous progress has been commended world over, yet the entire univerese is plagued with unsurmountable natural disasters like the wild fire in America, Huricane ,Psunami in Asia, issues of poverty in the developing continuents of the world. Malaria, HIV & AIDS are ravaging millions of people in Africa. I should not also leave this stage without mentioning the naging issues of Global warming caused by high level of carbon dioxide emission facing the whole world. Even though science has done so much in addressing some of these problems, more needs to be done
