Hold on......
There's also all the frictional losses in cables!
Cables are GREAT for simplicity but they usually run within an outer 'sheath'. This type of cable is called a 'Bowden Cable' and are the type you usually use on the throttle. You COULD use a simple 'exposed wire' but then you WOULD need 'straight line' cable runs or levers and linkages to turn corners BUT the 'space' between each linkage WOULD have to be straight.
The Adfvantage of the Bowden is that it lets your cable 'turn corners'. The HUGE disaadvantage is the fact that running one cable inside a sheat cuases FRICTION! It's also HORRIFYINGLY subject to grit and rubbish enetering the cabele and cuasing even WORSE friction. This can be aenough to stop the cable moving in ANY direction.
Next, the 'Bowden' allows fraying of the inner cable. This can go completely unseen until there is a catestrophioc failure of the cable.
Finally, fraying of even a single strand of the inner cable can jam the whole process.
Cables ARE great but, just like hydraulics, they TOO have drawbacks. Maintain BOTH (errr... either) systems PROPERLY and they EACH have advantages!
