It is has been WAY too many decades since my last ME classes to be confident in my estimations so I am wondering if someone can give me their opinion if I am going to run into trouble. The YT video (
The materials difference in thermal expansion is 1.7e-6 per degree C. So 2" x 1.7e-6 x 100d C temperature range = 0.00034" You will never notice at any place on earth. Grant KZ1W The YT video (URL be
Thank you grant. I was not sure how to interpret that linear expansion as my situation is using round tubing. Not sure if the diameter would change at the same rate as in a linear strip of metal. 73
Diameter grows at the same rate. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contestin
Technically the circumference does. If I did the math right in my head, that means the diameter changes faster than the coefficient. If I'm wrong, it isn't the first time. Nor the last. If I'm right,
Thank you everyone. From the sounds of things I should be ok. 73 Gedas, W8BYA EN70JT Gallery at http://w8bya.com (under repair) Light travels faster than sound.... This is why some people appear brig
I hate to be a big ignoramus, but why, if this is not an issue for Gedas' 10 GHz mount, is sweating joints that seem to be similar to his design a common practice in machinery design? Can someone he
If it was me I'd stick it in the oven and see what happens. If that didn't seize it up, then I'd put it in the freezer and repeat the experiment. 73 - Mark N5OT who thinks the best conductors are th
I'm not sure that percentage of expansion is the relevant consideration here. I would think that the gap between the cylinders (i.e., portion of the diameter) is the important part, and since the ex
Expansion in an isotropic media such as most metals is the same in all directions. Think of enlarging something for printing by a fraction of a percent. Everything gets larger by the coefficient of e
