Thank you.
I do not know what to do with the differential equations.
I was assuming a machine could be made with the first and second differential, with an output max of 13 units.
Would you know how to make a machine with this equation?
I have no idea.
Let me know,thanks
If you know phi it is about 1.618...=2cos36.
The equations when x=phi which is equal to 0 is x^2-x-1=0.
I took the first derivative squared and the second derivative cubed.
The equation with x=phi is:
[2x-1]^2+2^3=13
Check for yourself, if you fill in phi you get 13.
Anyway, I do not know what...
Which is better and how to do it?
Make a spaceship an electromganetic field and go through a sensor so at the end of the race it must pass between the sensors to win, and what sensor would you need for very close width. Saying the spaceship is 20ft wide and both sides must be between the 80ft...
We need a full matrix solution for the problem in the picture. 3d matrix. Eigen values, moments, inertia, forces, etc. I have not done this sort of matrix before, please guide me.
Also, the next part to take note of which I do not know is how to weight the masses differently because the actual time we need the mass is when it has T1 acting upon it.
I want the mass to be able to counteract a maximum amount of torque, T1.
1) The cone with sphere end, the object, is unmoving until a torque, T1, acts on it.
2) We take mass of object, m, and play with the density, inertia, and center of mass to optimize an equation to find what values of what...
Sorry about the picture, the force is on the wrong side. Just pretend the force is on the other side.
What I want to do is create a 3d cone with a 3d spherical cap, and in order to take on the most force times an arm or torque, I want to have a the perfect densities at different locations in...
My goal is to fight the max amount of torque with the weight by having different densities at different places and by keeping the z center of mass low.
I need to find the answer out in terms of the three angles, and the final answer must not have a substituted angles such as 45 degrees.
I need...
