Sm0ky2:

Would this same shape benefit the upper part of the curve (in attraction)?

I'm thinking yes, it will, As Graham pointed out earlier, the attraction end should be angled away at the opposite end. So that it is further out at the 3:00 position.

Anyway....back on the actual content side of the aisle.......

Has anyone checked out the latest video and seen what more weight (mass) is doing?

Wood/plastic stops just a little past 9:00 with a 1:00 drop.

Metal pipe stops at about 10:45 .

Definitely something to be said for the "flywheel effect" (more mass).

Downside is mags have to be MUCH beefier.

Any insights/opinions on this out there kids?

If comparing a generic larger mass to a smaller mass then the gravity force automatically increases so that both objects can accelerate at the same rate [that's the strange thing about gravity force].

Opposing this rate of acceleration are losses - in this case frictional losses of windage & pivot/axle friction etc - if we assume a comparison of wood & plastic to metal to have different masses but same shape & volume then the windage factor will be equal for both - the pivot friction will also be similar except that the heavier mass will have greater inertia & weight, therefore slightly higher frictional point loading losses.

Although both objects will have different inertias this won't alter the final arc height they could individually ordinarily achieve because although the heavier mass has more inertia it gives it up less readily once underway [slow to start but doesn't stop easily].

So the more massive object swings higher [all else being equal] because the force from gravity is greater than for the less massive object & they are roughly opposed by similar loss forces of friction from windage & pivot friction etc - therefore, there is a large proportional difference between the two scenarios resulting in the more massive object swinging higher on the clock face than the less massive one.

I am building a PPM using elastic bands.

I figure on using that power experienced when releasing a stretched elastic.

Should work I reckon.

PS: Preface the statement above with....'Would you believe....'

[fletcher]

You can use elastic systems in some circumstances e.g. if you have an external heat source to warm the elastic band [if it is rubber bands] on one side of a vertical wheel - thermal warming of rubber causes it to shorten in length & thicken which produces contraction & tension & torque - when the rubber band cools it elongates etc - if a cam is employed [for example] a slow turning thermal engine can be made.

Weights & springs/elastic bands etc is a completely different story, IMO.

I hate to rain on your parade here Newt but I really think you need to see a psychiatrist if you've been emotionally hurt by Archer's efforts to build a perpetual motion device.
Where are you based? I could refer you to some of my friends in Australia or New York. Just promise to put on the white coat when they ask you nicely.

I was referring to you and Chet. The kool-aid drinkers. The ones being duped.
