      [​IMG]As an engineer, do you consider yourself to be a member of a creative profession ?
      Interested to know how engineers perceive themselves.... The professions most people associate with creativity do not generally include any of the engineering disciplines, and yet to be a professional problem solver, which is what an engineer is fundamentally, means we must be as creative as possible. The best engineers aren't necessarily the ones who can follow the rules laid out before us, but the ones who find the best
      [​IMG]Idea to improve chain design I am trying to design a chain that should hold a mass against a cylindrical pipe(vertical). Each link has a wheel, thus the mass can be made to go around the pipe by manual force. My problem is that, each time the mass goes around the pipe and back to its initial position, its vertical position on the pipe has come down a little. I need to prevent this from happening. I am able to tighten the chain to reduce this problem a little, however I am not able to eliminate it.
      [​IMG]Calculating torque on hardened pins This seems a simple enough task to determine, but I don't think I'm doing it correctly. I would like to determine how much torque a pair of pins can handle. I am using the pins to transmit torque from one rotating mass to another. The pins are pressed into one mass and assume a close tolerance fit in the other and the two masses are flush against each other. I'm given the double shear load rating of one[​IMG]Have anyone tried Freelancing jobs before? I'm asking if anyone tried the Freelancing jobs before?, just was searching on jobs i can do online, and get paid from, and got the website " WWW.freelancer.com ", where you can find engineering jobs there, you can do, and get paid against doing it, but in a way is explained in the website, so here is my question:

It is an API 610 Centrifugal Pump (material is CS) 1 - The operating temp. is 40C. & as the boiling point of Naphtha is 25C, alot of cavitation might occur......
      [​IMG]Building a big servo Maybe someone can help me to solve this engineering problem. How you will see on the photos I need to add this little potentiometer to the big gear. It will give me the information about the position of big gear(the biggest with the hole inside). Off course it is better to instal this potentiometer inside the box, but it can be all so outside.[​IMG]CALLING ALL INVENTORS! - New Sky TV show MAJOR NEW SKY TV SERIES IS LOOKING FOR YOUR INVENTIONS!
