No, you missed something: the device is theoretical for simplify the calculations:

No mass: no differential equations
No friction: so difficult to compute with friction...

BUT, it is very important: it is possible to have a mass for all the parts. And friction too.

It is a theoretical simplification to simplify the calculations not because at final this device must be without mass and friction. If I'm right with this theoretical device, I'm right with a device with mass and friction.

If you take away some digits/letters from a mathematical fixed formula,
how and what you will get a/-s result ?
