Yet to be unequivocally demonstrated after 90 years of patent publications in the area, a mechanical propulsion device is presumably a combination of mechanical parts in a rotary configuration that on rotation generates net linear thrust with application of torque.
how do you when you have crossed a threshold for a mechanical device
Light pen is a mechanical or optical device? i don't know answer for this
The rocket engine is the device that converts chemical energy into the mechanical energy. A firecracker also converts chemical energy into mechanical energy.
name a device that convert the mechanical energy into electrical energy
