Hello. I am taking an Engineering Introduction class in college, and our project is to build a truss bridge that can sustain a 2000 lb load. The length is 24 in exactly, and the height and width can not be more than 5 inches. Its a two parallel symmetrical level truss bridge. Do you have any advice before my group starts on the project building? Thanks.

Hi all...i am mixing epoxy ( viscousity 50,000 ) with tiny magnetic particles. I am using hand mixing.For small amount, there is no problem, but for larger amount I am facing some problems. most of the time metal particles are deposited at the bottom of container.It is importent for me to mix both evenly as I have to add controlled amount of magnetic particles. I can not place the shaft-end to be touching as there will be friction between shaft-end and bottom of container.but I place it as near as possible. What I need is to scoop up those deposited at bottom at certain frequency. I dont want to do it manually as the amount is large.Now I am using Anchor stirrer and still facing those kind of problems.Please recommend me some type of shaft which can mix material bottom to top..Thanks...

The oxygen molecule, O2, has a total mass of 5.30 10-26 kg and a rotational inertia of 1.94 10-46 kg·m2 about an axis through the center of the line joining the atoms and perpendicular to that line. Suppose the center of mass of an O2 molecule in a gas has a translational speed of 580 m/s and the molecule has a rotational kinetic energy that is 2/3 of the translational kinetic energy of its center of mass. What then is the molecule's angular speed in rad/s about the center of mass. Thanks a lot for your help!

ok my science teacher and i have a bet that i cant make drinkable wine in an hr to 30 min . were going to put yest in frute juice and put a balloon over the glass and let it fill up the balloon. as we all know this is LIKE the way they make wine giving more sugar and what not . im just wondering if this can even happen . i think if i bring in a hair dryer and put it to the glass this will speed up the process . plz tell me what you think !!!!!!!!!!!!!!

Toward the end of the 90,s a French engineer was able to take pictures of chakras with a video camera.

A Spanish magazine named Karma printed an article about this.

That is all the information I have and I would like to know more. Anyone in the science community has heard of his name and where I can find those shots ?

All help will be greatly appreciated. I am on a strict deadline.

Thank you !
