Leafy’s bar vs. Bessler’s crossbar

[Leafy]

Why does it has to be a crossbar? After reasoning, I came up with a setup that could compete with B’s crossbar.

Sim is welcome. I have a bar with mass A and B. Mass B connected to a square lever that hit ramp C as it turns. Mass A is larger than C.

Example:
mass A = 2 ton
Mass B = 1 ton
Bar weight = 5 ton
Ramp C is stationary to cause a frictionless shaking. Lol

Granted it wont be balance as a crossbar, but it should be a runner.

Leafy, I always enjoy looking at your designs. You have an interesting perspective that makes things interesting.

You should build and examine this mechanism, and understand why it does what it does.

ADD: What theoretically is the difference between the operation of your mechanism and MT13?

[Leafy]

You got me Tarsier, it is MT 13 related. My operation theory does not required the full assembly to run.

The first drawing only cause the B mass swinging and the result is uncertain. So I redraw MT 13 with most minimal component.
I don’t like building unless I’m very certain, I like to learn with just thinking.

The difference between MT13 and this is that it doesn’t operate by OOB, it involve wheel inertia, OOB, and counter torque happens at the same time and that’s exactly what I drew.

[Leafy]

Actually, you cannot fulfill the OOB, wheel inertia, and counter torque at the same time with one bar, at least not 360 degrees.

B is correct with crossbar. So I redrew MT13 with minimal components to work.

As you can see, each time a weight is lifted it involve taking the wheel inertia while OOB presented.

[Tarsier79]

The thing to take from MT13 is that each weight gives to the wheel exactly what it takes from the wheel to lift it.

I wanted to post Crazy Daves youtube pendulum tests, which are quite interesting but I can't find them.

regarding CF/swinging from a pendulum driving a wheel.

I suppose we can sim this experiment:

A 1kg ball dropped on a square lever. The lever push on an identical ball. Calculate the total energy after collision.

Released from what vertical height ? What is the height of the horizontal of the 'square' lever ? What are its length and width dimensions ? What is the levers mass ? How far from the lever pivot does sphere 1 "Effort" contact it ? What is the distance from the lever pivot to the contact point of the sphere 2 "Load" ? What is the elasticity of the spheres and the lever ( 0.00 to 1.00 where 0.95 is equivalent to hard steel) ? What is the static and rolling frictions of the parts in contact ? Is air resistance zero for the exercise ?

Maybe time for you to start thinking about downloading a free online version of a physics kinematic program Leafy - some here use Algoodoo. Do a search online - there are many available to choose from.
