What is the minimum Tube Engagement that is necessary for a connection between a Fibreglass Tube into an aluminium tube that is in cantilever.
Fibreglass tube is 76.5mm OD 6mm Wall
Aluminium Tube is 77.0 ID 6mm wall
I am trying to make an electrical connection between an electrical cable and aluminium, currently brass pins are soldered to the aluminium and the wire is soldered to the pin.
We need to move away from the solder used to join the brass pin to the aluminium as it contains lead, but no ther lead...

I need to calculate the natural frequency of a 19mm Dia x 1.6wall x 720mm long Fibreglass Tube. I am trying to calculate the critical speed of of this member as it is developing vibrations at around 80km/h (wind speed). I would to see if the critical speed is close to this 80km/h.
If it is I...
I have a Car Mounted Antenna Dia 19.0mm x 1mm Wall x 720mm Long which creates a vibration at approx. 80km/h. The Antenna has a fibreglass thin walled structure. I believe the vibration is due to the natural frequency of the material.
Can the velocity be calculated to determine critical speed...
