And aside from the steering ratio, as Posted by MetroMPG, when you try to steer a power steering equipped vehicle without the engine running you are also forcing fluid to flow in the steering unit against a resistance. This can be quite extreme in some vehicles.
The same is true of power brakes. In my little 4 cyl. GMC Sonoma it is impossible to stop the vehicle after you have exhausted the vacuum reservoir of the brakes with engine off.
In other words, at least with some vehicles (all I have tried), steering and brakes operation without the engine running is nothing at all the same as that same vehicle would be if it were not factory equipped with power steering and brakes. It can vary from being quite difficult to even being impossible.
