Coordinate systems and phase shiftsHey! #2 20051206 02:21:31
Re: Coordinate systems and phase shiftsWaves are graphed as trigonometric functions. Why did the vector cross the road? It wanted to be normal. #4 20051206 18:15:47
Re: Coordinate systems and phase shiftsThanks for your answers, however I am still a bit stuck. I'll try to give a more thorough description of the problem. In the attached picture two vessels, A and B, are illustrated. The blue vectors illustrate the waves and how their angles of attack are measured. When the waves hit the vessel, there will be motions in 6 degrees of freedom; surge, sway, heave, roll, pitch and yaw. #5 20051207 09:32:07
Re: Coordinate systems and phase shiftsI am thinking that you will not be able to use a single equation to give you all of those motions in threedimentional space. For example, the formula that mathsyperson gave you is generally used to find the position of a particle within a wave. However, this relates to only movement along the y axis for a specific point in time. #6 20051207 18:20:52
Re: Coordinate systems and phase shiftsThanks for a a well thoughtthrough answer! #8 20051209 12:40:09
Re: Coordinate systems and phase shiftsPoor Danster, not only do you have to create seperate functions for each axis but you also have to have a variable within all of those functions which changes them depending on the location of the source of the wave.
