Shouldn't it then be named G-spot? If a program of such a name were to exist, would any male users be able to find it, let alone use it?
For me, as a non-engineer, this is quite difficult to get my head around although the example of the differential given above is a useful one. The bit I don't understand is why the secondary motor to control the ratio doesn't require the same power as the primary motor. For example, given the differential set up described above, wouldn't the second motor (where one of the wheels would normally be) have to provide just as much power as the primary at any speed other than full speed (where the secondary motor could be locked)?
I guess the bit I'm missing is how speed but not torque is taken out the system. Anyone care to provide a handy link with some background reading? (Something other than "go get an engineering degree"
