Re: Bessler's secret (probably)

Broli, I think it is wonderful that you share your thoughts for free, and i would encourage everyone to do the same. Sharing our thoughts is one thing, but insisting everyone agrees with them, is another. I can't see why you are getting all excited, about some gears that make things go faster. I sh...

Re: Bessler's secret (probably)

It’s been speculated Bessler might have used gear trains to achieve the quick acceleration his wheels had. The weights themselves don’t seem capable of that much start up torque unless he was using a lot more than we think. There are some MT drawings that have gear trains but the notes say the usua...

Re: Bessler's secret (probably)

I am giving away too many secrets but hey there is no rules on giving stuff away for free. I guess I will keep retrying until someone gets it. Back to the hard mechanics of things I realized the rotational version of the rotational lever is much easier to grasp, but more importantly to animate. Ther...

Re: Bessler's secret (probably)

https://www.britannica.com/science/rolling-friction The main source of friction in rolling appears to be dissipation of energy involved in deformation of the objects. If a hard ball is rolling on a level surface, the ball is somewhat flattened and the level surface somewhat indented in the regions ...

Re: Bessler's secret (probably)

You say more friction is better? Wouldn't that cause less slipping? I'm thinking more Bull Shit would cause more slipping. Sorry Broli; I think you are out of your mind-------------Sam Rolling friction and Sliding/Slip friction are one and the same. The only difference is geometry which leads to mo...

Re: Bessler's secret (probably)

Hi agor, Slip friction is not less friction it's In fact more friction! I highly recommend people start at the basics and study the force of friction the force which is the basis of all forces a force quickly glossed over in classes. Here's a helping hand. Sliding friction is defined by the relative...

Re: Bessler's secret (probably)

Right Tarsier .. the Work Done f x d is greater than the KE gained by the SB, regardless of the velocity of the final segment n.b. equal in a perfect no friction environment .. in the case of the DWFTTW cart ultimately its final velocity is dependent on its aerodynamic drag losses ( minimized ) wit...

Re: Bessler's secret (probably)

If you dont succeed as a bad teacher you keep trying perhaps some day your students will have a breakthrough. Attached is an improved version with an algebraic algorithm to help out.

Re: Bessler's secret (probably)

Can anyone provide me a link in PM for wm2d, a trial should do. Thank you.

Re: Bessler's secret (probably)

I have a saying. There is no such thing as a bad student only a bad teacher. And yes this teacher has failed once again. However the universe gives us infinite chances to try again until we succeed. So let this foolish teacher try again. I arguably forgot to talk about the equally important part, ve...

Re: Bessler's secret (probably)

Hi Fletcher thanks for doing the Sim work. But as I said before multiple times. The top beam must remain FIXED or else there indeed is no extra energy. When it's fixed and the cart is given a small initial push by "gods hand" the top wheel MUST slip on it and the slip frictional force from...

Re: Bessler's secret (probably)

As I asked earlier. Does wm2d support sliding friction? If not then all you will see is that there indeed is a velocity difference between the ground and air beam. You must fix both to the immovable earth but if the air wheel cannot slip on the air beam, then it will lock up and nothing will happen....

Re: Bessler's secret (probably)

Something aint right in the simulation, i think. The diameter of the wheel on my screen is 20 mm which gives 62.8 mm circumference. The Yellow circle rotates a bit over half a turn, so i think we can say 33 mm without exaggerating. The blue rectangle only moves 24 mm. The YouTube video Fletcher sho...

Re: Bessler's secret (probably)

Looks like I need to give the patient another shock to bring him back to life.

I have always been bad with words but I love making illustrations to translate my thoughts to others. Hopefully this one translates better.
