I am trying to use a linear guide for a door in a vacuum chamber. It is aluminum with a clear hard anodize surface. The pressure of the chamber will be 3x10-5 Torr and Temp. will be 150F. I was told not to use anodized aluminum because of its porosity but it doesn't make much sense to me. I...
Hello,
I am looking for a cheap ($200) extensometer to measure strain of a bike spoke. Are there any extensometers available that will simply attach to the spoke to measure strain? The max load will be 50lb.
Thanks.
Hi,
I was looking for the right materials for a rack/pinion design to open a door. Here are some constraints.
Temp=160F
Pressure=10^-6Torr
all parts must be low outgassing, nonmagnetic and electrically nonconductive.
I thought of using aluminum for the door/rack/pinion since it is...
Hello,
I am looking for a motor that will be used to open an aluminum door. There will be a strong magnetic field present so I was looking toward a piezo/ultrasonic motor. I plan on attaching a pinion to the motor and a rack to the door. Does anyone know where I can find a motor for this...
