Bessler Wheel question

[Tarsier79]

If you feel they are essential, you must believe they perform a specific function in order for them to be so. What do you think that is?

Dear helloha,
There are so many ways to use the springs!

One end linked to the axle of the primemover, the second end to a pendulum, per example.

unfortunately, there wasn't many options to use springs in a simulation environment, ... still trying to figure out how to sim a torsion spring ... LOL

Helloha,

Some time in the past, a WM2D user made a post about using the motor symbol set with low torque running backwards to imitate a spring. As to how you would control the on-off, I leave up to you and any help you can get.

I know nothing about the program other than knowing how to open and run your .zip files. Knowing nothing means I am putting my foot in mouth by even posting this, but it may be of help, or arouse a response from an experienced user.

Tarsier79, I believe springs give possibilities in motion/results that may be needed, actions not available with rigid rods/links/levers/cords/chains etc. Springs we know do not produce any excess but they can 'do things' not achievable by other means, ie store/delay, advance/accelerate, pulse/harmonise, etc. I think its the case that most mechs are stable or chaotic but not both, yet a spring pendulum can display both types of motion?
And of course bessler admitted they were used, but not simple wind up spring obviously.
If he says his swinging/falling weights are the motive power, then we need something like springs to give a resulting 'unusual' motion that is eternally off centre.
May have seen these before? http://www.myphysicslab.com/pendulum_cart.html and http://www.myphysicslab.com/spring2d.html the java applets for these are ok to allow.

Hi Wheelrite,

Those applets are brilliant little programs !

With the graphing capability , it really demonstrates how ‘non chaotic’ a spring/pendulum combination really is over time .

Playing around with this program demonstrates fairly clearly to me that if all the forces involved are known and handled over time mathematically , getting chaotic motion doesn’t appear to be that easily obtained. The graphing seems to show that eventually the movements are symmetrical on a suitable time scale.

I think if I come across what appear to be chaotic results in future I’ll be looking for a force input I havn’t been recognising .

I think I’ll play around with them for a little while longer , then go back to work : )

using the motor symbol set with low torque running backwards to imitate a spring.

thks for the info, i'll try it out

Helloha .. you use a separator [between parts], with spring dampener element, or rotational spring element etc.
