    Waves - Power spectral density to amplitude

    Hi all, I am trying to simulate ocean waves on a 3d grid of points. I have recently discovered the Pierson Moskowitz spectrum which will give a wave spectral density (ms/hz) for a given wind condition. I am trying to represent this by using a large number (say 64) Gerstner waves. Each wave I...

    Undergrad Calculate Arm from Torque and Force vectors?

    Will the following give me a valid possible position even if the force isn't perpendicular to the arm? - Normalize( Torque cross Arm ) * ( Torque.Magnitude / Force.Magnitude ) If so, I do know roughly what plane the force should occur on so I am wondering if I can find my force position using...

    Undergrad Calculate Arm from Torque and Force vectors?

    Hi all, If Torque = Arm cross Force Is it possible to calculate the arm from the torque and the force? I have tried to solve this using cross product of torque and force to give me the arm direction. Then normalizing the result and multiplying by torque magnitude / force magnitude. However I...

    Graduate Wing pitching moment ( torque not around cg ) - head hurts

    Thanks Filip! :) Appreciate you taking the time to explain all this - I think I am slowly getting there :) I already have the lift and drag working, the aircraft flies along quite nicely using just lift and drag from the aerodynamic center but I want to include the pitching moment properly...

    Graduate Wing pitching moment ( torque not around cg ) - head hurts

    Hi Filip, Thanks for taking the time to reply! Will there not be a translation from pitching moment being offset from the cg then? i.e will the plane not pitch around this point rather than around the cg? Edit - I have just done a bit more reading and I realize torque and moment aren't entirely...

    Graduate Wing pitching moment ( torque not around cg ) - head hurts

    Wing pitching moment ( torque not around cg ) - head hurts! Hi all! :) First post! I am currently coding up a basic flight simulator for fun. It is all going well so far - and certainly improving my rusty physics knowledge. I break the wing down into elements calculate the lift and drag on...
