    Define Circle Knowing Two Points and ARC LENGTH Only.

    There doesn't really need to be a context. You know the length of a chord on the circle and the length of the arc segment between them. I did some digging and did finally manage to find two solutions. One uses Newton's approximation method and the other uses and taylor expansion...

    Define Circle Knowing Two Points and ARC LENGTH Only.

    I am having trouble doing exactly what the title says. I have two points and the arc length between them (this is a bending beam type of a situation). Essentially I know where the ends of the beam are and how long the bent beam is and I need to get the equation of the circle. And yes I...

    Antennas for a High Altitude Balloon

    Hey, I'm looking for the optimal antenna to transmit in the 900 Mhz range from a high altitude balloon. The transceiver I have says it is capable of 40 miles LOS with a 15 dBi antenna. Can achieve this? Can I just hang say a 100ft wire from the bottom of the balloon? Do I need a different...

    Forklift Stability: How Much Weight to Keep from Tipping?

    I understand that I will probably need to give some more variables here, but I am not sure what they are. in any case, my question to you all is this: As shown in the diagram below, realistically, how much weight should be placed at the x to keep this forklift from tipping over. I am working...
