Homework Statement In lab we did an experiment where there was a 12v D.C. power supply in a glass dish filled with water. We set the + and - terminals in the dish and a piece of graph paper underneath. With a volt-meter we hunted for certain electric potentials such as 2V, 4V, 0V, etc and wrote...

well I have ordered the gear motor I linked too under the components section of one of my previous posts. 90N cm will hopefully be enough to drive this thing according to an online calculator it should in theory be able to generate a force of about 9N-10N.The teflon, bearings and such are still...

Teflon has excellent chemical resistance(critical), high temperature resistance, and low friction. I got a 1" OD by 1 foot long PTFE rod for 13 dollars. Granted that is expensive, the cost of a rotory evaporator is far larger. What do you mean by a gear motor? Isn't that what I have in the post...

Wow I am surprised at the helpfulness and how fast the replies have come in. I'll have to stick around this forum. I have attached the design I am essentially following. The picture is a top-down view. design A is the motor B is the wooden support with a bearing slot bored and glued into...

Hi all, brand new to the forums. I'm a student of chemistry so I am very unknowledgeable about mechanical engineering and need some help. Not asking for spoon-feeding. What I am trying to accomplish is fairly simple(I hope). I would like an electric DC motor to turn a 1in diameter teflon...
