Have a nice day
I study chemical engineering, but practice at the Department of Theoretical and Applied Mechanics
I can try to help you if you specify the problem more specifically
Please contact me for further discussion.
Excellent understanding about free body planetary space mechanics and good imagination skills using 3D CAD models.
Please define the problem first and then let us discuss on phone.
Please don't hurry and pressurise for forcing a fixed time frame but surely can deliver perfect results in a finite period.
Basically being a Mechanical Engineering Teacher founded on thorough understanding of theoretical Physics.
