Is There a Solution for 6 Degree of Freedom Solid Body Movement Equations?

In summary, the conversation is about solving a system of equations related to 6 degree of freedom solid body movement. The equations involve rotations around the x, y, and z axis and have constants k, m, and n. The solution is complicated and may not have an explicit form, even with known values for the constants. The person asking for help does not have a full copy of Mathematica but may be able to obtain one. The other person also has a full copy of Mathematica but the solution is still difficult to obtain.

Hi, I ended up with the following 3 equations that relate to solving 6 degree of freedom solid body movement. The equations relate to rotations around the x, y and z axis (which is far more complicated than translations). Is there anybody that knows the solution or can figure it out (i am just an engineer and have not done proper maths for about 30 years!)?
Thanks
Anton

k, m and n are constants:

The following Mathematica command solves the system, but the solution is horrendous:

Code:
Solve[{x==k1+k2 z y-k3 y-k4 z,y==m1 +m2 z x -m3 x-m4 z,z==n1+n2 x y-n3 y-n4 x},{x,y,z}]

Do you know the exact values of the constants? If so, I think the solution would be much simpler in form.

Thanks, that was so quick! Can you provide the solution please (I really don't mind if it is horrendous!:))?

I do know the exact values of the constants but I think it unlikely that this will simplify the form...

I attach the full background, I'm sure solutions must exists for this but after much searching I still have not found them.

Unfortunately, I don't have a full copy of Mathematica at the moment. The best I can do is the Wolfram Development Platform, which is not giving me enough server time to display the entire thing. Stay tuned. I may be able to get a full copy of Mathematica through my research connection.

I have a full copy of Mathematica. It doesn't help, the system is fugly.

Thanks guys, even though it may not be the result I was hoping for at least now I know that apparently it does not have an explicit solution. Appreciate the answers.
 

FAQ: Is There a Solution for 6 Degree of Freedom Solid Body Movement Equations?

What is the solution of 3 equations?

The solution of 3 equations is a set of values that satisfy all three equations at the same time. It is the point where all three lines intersect on a graph.

How do you solve 3 equations?

To solve 3 equations, you can use the substitution method, elimination method, or graphing method. These methods involve manipulating the equations to eliminate a variable and then solving for the remaining variables.

Can 3 equations have more than one solution?

Yes, it is possible for 3 equations to have more than one solution. This is because the three lines may intersect at multiple points on a graph, resulting in multiple solutions that satisfy all three equations.

What happens if 3 equations have no solution?

If 3 equations have no solution, it means that the three lines do not intersect at any point on a graph. This could happen if the three lines are parallel to each other or if they are all on the same line.

Why is it important to solve 3 equations?

Solving 3 equations is important because it allows us to find the values of variables that satisfy all three equations at the same time. This can be useful in various scientific and mathematical applications, such as finding the intersection point of three physical objects or determining the optimal solution to a problem with three variables.
