Time travel thread, Hey ho let's go!

no...not really, what your talking about is like precessional drift, in relation to the earths spin at it's poles...the horizone we look at 'goes backwards' thus giving the references in astronomy and astrology...thats what happens with the 'creep'...

what I mean is that when you hold a power drill and boost the switch ie turn it on...at some points the momentum of the accelerating commutator within the drill seems to counter the weigh of the drill...ie the drill feels lighter...I don't think it feels lighter because it's tricking your brain into 'thinking' it is...I think it's because (as you say...the inertial effect in one direction...ie clockwise...actually helps to lift the drill in a counter clockwise direction, which would be perfectly feasible...)
I'm not saying thats magic...what I am saying is...that in a 'commercial' application...harldy anything has been done to research that...

If you are talking about holding the drill so that your hand is off to one side of the drill's centre of mass, then as well as supplying a force to oppose the drill's weight to keep it up, you have to supply a twist to stop the drill rotating in your hand until it dangles below your hand. You do that by having one part of you hand push down on the drill and another part push up. The part that is pushing up to supply the twist is probably the same part that is pushing up to support the weight of the drill.

When you switch the drill on (or off) you have to supply another twist to stop the body of the drill rotating the opposite (or same) way as the bit. Depending on which way your hand is off centre, and whether you are turning the drill on or off, that twist can add to or subtract from the twist needed to resist the off-centre grip. If it subtracts, then suddenly the bit of your hand that was supplying the up force only needs to supply enough to resist the weight, and so the drill feels suddenly lighter.

Does that work for you?
