I'm not worried about the bolts failing in shear, it's an interface loads study and I need to know what loads go into the structure.
I'm using traditional fasteners. I like the strain gage idea, but I'm unsure where to place the gages.
I'm hoping that someone it familiar with a commercial...
I'd like to measure the tension and shear forces on several bolted fasteners during a static test.
I've looked at these and similar products: http://www.innovationplus.com/index.php
...but it is my understanding that these are only good for clamping force (aka tension force).
Anybody...
From the article:
"High altitude air cooling has always been somewhat of a mystery to the uninformed."
I laughed, in this case I am definitely the uninformed. Good find! I wish there was more on free convection rather than forced, but it's a great start for the properties I care about.
After some digging I've been doing exactly that. Short answer is, it depends on a lot.
Long answer is that it depends on gravity, thermal expansion coefficient, kinematic viscosity, thermal diffusivity, absolute viscosity, and of course temperature and density.
Has anyone done this before? Can...
Interesting. I had been assuming that the power would be dissipated evenly over the length of the cable. What you said makes sense now that I understand attenuation more. So the front end (power-in end) will dissipate more power.
I'm still hung up on the effect of length. Thermal resistance...
I am trying to calculate the maximum power of a coaxial cable, based on heat transfer parameters and limiting temperatures of cable components. I've determined that a certain heat load on the conductor surface (in Watts per inch of cable) will put the dielectric above its operating temperature...
I am trying to develop a spreadsheet to calculate a convection coefficient with altitude as one of the inputs. What variables should I consider? The most obvious are pressure and temperature, but I'm sure there is more to it than that.
