Is kinetic energy enough to propel objects in 3D space?

AI Thread Summary
The discussion centers on a 3D motion generator concept called Anti-Gravity Transportation (AGT), with the creator seeking insights to enhance its design. There is an acknowledgment of potential propulsion and sustainable energy from this idea. However, the response highlights that the concept resembles a perpetual motion machine or "anti-gravity" device, which contradicts established physics laws. Consequently, the thread is locked due to the nature of the topic. Further clarification can be sought through private messaging if needed.

I've recently created a 3D motion generator (Anti-Gravity Transportation (AGT)) in 2D/3D design. unfortunately my current physics knowledge is not advanced enough to take this machine to its maxium potential. i can concieve perpultion and sustainable energy coming from this idea. my question comes in the design its self. for anyone interested i will gladly show more for your insight.

Welcome to PF.

What you said is a bit vague and confused, but sounds like a perpetual motion machine or "anti-gravity" device. Discussion of such topics is not allowed on PF because such devices violate the laws of physics. This thread is locked. If I've misunderstood something though, feel free to PM me with more specific information about what you want to discuss.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
