Raka has a uv inhibited epoxy.
If there is an emergency it is likely serious hams will be operating stations with antennas that can reach you. If you are in a reasonable...
Drag ratio, R, is the ratio of the upper CdA to the lower CdA. (where upper is above the break).
The force trying to separate the rocket at burnout is given below. If you just consider inertia forces you can set R=1
This force can be - or +...
No, the inertial separation force is a function of the difference in mass between the sections and the acceleration (deceleration)...
Well if you want to split hairs you actually don'r feel forces but you feel deformations.....forces are not directly observable.
In the rotating frame you a 'feeling' an acceleration not a force. They feel the same.
The acceleration on you is caused by the static friction...
At what altitude?
Einstein say gravitation forces are not real either. It just an apparent force due to space-time distortion by mass, like the water in the pail.
All this confusion originated by Jean D'Alembert in the 1700's who attempted to convert dynamic problems into static problems by introducing the...
If at the top of the vertical loop you eliminate (somehow, thought experiment here) the bottom of the pail, which way does the water go?
Centrifugal is the "apparent" force keeping the water in the pail. The pail applies centripetal force to keep the water going in a circle. Its...
Centripetal or centrifugal force is the force required to keep a body moving in a circle. The body has a constant acceleration magnitude pointed...
+3 That barely qualifies as damage.
Ok where is the party then tonight?
If the pivot was frictionless and the canards massless then there would be no AOA. But there is friction and mass so there will be some AOA....
We launch AT an airport. No faa involvement is needed for class 1 other than vfr rules.
1. if you make something and sell it, you might be a vendor.
2. If you buy at wholesale and sell at retail, you might be vendor.
