The discussion centers on the physics of flywheel launchers, specifically how rotational kinetic energy and angular momentum influence projectile velocity. Key factors include the role of slippage due to friction, the effects of compression on momentum, and the relationship between RPM and torque. Participants clarify that while torque is essential, the tangential velocity of the flywheel primarily determines the linear velocity of the projectile. Understanding these dynamics is crucial for optimizing the performance of flywheel-based systems.
PREREQUISITESEngineers, physicists, and hobbyists interested in the design and optimization of flywheel launchers, as well as anyone studying the principles of mechanics and energy transfer in projectile systems.
cardboard_box said:I already know some of these variables, but I am not fully sure I get every effect of them and I still don't understand the importance of RPM.
You solve the problem as described in Post #38. Is the real here here that you don't know how to solve that problem?cardboard_box said:so for example, if you are given a projectile which you know everything you want about, and are told to fire it at this and this velocity and fire this and this of them at this and this rate, how do you decide what wheel do you use?
...how exactly do I go about building such a function? specifically how does the velocity of the wheel change the velocity of the ball?
