I have Master Degree in political science... But I'm intereted in physics and electeonics stuff... Right now I'm starting my on home school in physics and electronics. Your video is helpful and inspiring.. Thank you very much..

A simple version of the old fashioned saw mill, well done
Great video, thanks for explaining! I found my way here trying to understand Alfadan's large displacement, inline four engine they are developing. Seems the traditional connecting rods have been replaced by some proprietary Scotch yoke. Paired up with the cylinder head being valveless, this engine sounds promising!
It has been very very educative ,no theory required
Well done. Am going to use this for a project I am working on. Thank you for posting.
Beautiful. Love your little models and mechanisms.
✌
It is a very simple and good projects, I am very proud of you .
This is Shreeshail Pujari.
Fcuk you Shreeshail Pujari
Can anyone tell me how to calculate the force of the pushing rod given the Torque of the motor?
Pretty nice work and also a pretty good show and tell. Bye bye Toni
Another great device to build with the kids, thank you
what's at the bottom of this tool which is attached to the wooden wheel? does it have small wheels at the bottom to slide on the table or bearings?
Very nice device! Thank you for sharing!
Para aquellos que no tuvimos la oportunidad en la vida de realizar estudios respecto a este hermoso tema de la mecánica ,esto me parece una maravilla
Esse sistema numa roda d'água numa bomba com 2 pistões , é muito eficiente!
What is the point vs. a standard engine crankshaft mechanism? To avoid the sideways pulling force on the piston? But it is replaced with sliding friction between the pin and the slot.
good model...
Try sealing the cylinder side and adding valves to turn this into an air compressor
Hi, i'm from Indonesia

Yes I have found it interesting 👍thank you very much
Wauw, simple and elegant. Thank you.
The scotch yoke is not found in regular combustion engines. There is only one from the 1940´s which was never build because it had all sorts of problems, but no modern engine uses this mechanism.
Cool video, appreciate about your creation.
thanks for sharing
I like this project .. good job
Thanks
🤨
Nice, thanks for sharing !
Yes it is good but,
What is the specification of the motor used in the project
Great video!
Also I noticed you use plastic tubing over the cam rod. Do you have to do that? I have not seen that on wooden models.Thanks! This is the best video on making one!
Probably to reduce wear on the surfaces sliding on each other. It may also reduce the clicking noise when the pin breaks contact with one side of the cam rod and makes contact with the other side when changing the direction of the linear movement.
Any info how this mechanism used in motor engines?
It can be applied on diesel and gasoline engines/vehicles
( ͡° ͜ʖ ͡°)
Lovely mechanical action to watch. No, BEHOLD!!
👍😎
I need it to brush my teehts.😁
Loved it, thanks.
Ingenious!!!
Sliding friction at four points. What is the advantage of this set-up over an ordinary crank mechanism?
1. No movement/inertia of the linear moving parts in any other direction, so less stress when reversing direction.
2. The linear output is purely sinusoidal-the piston exactly follows the pin on the wheel, whereas with a crank the distance between the pin rotating on the wheel and the piston varies due to the varying angle of the connecting rod (from 0° when the pin/piston is at TDC & BDC up to a maximum angle at 90° away). This results in a lower linear acceleration of the piston when moving away from TDC/BDC until mid-stroke, and then higher acceleration from mid-stroke until the end of the stroke (the higher and lower being relative to the acceleration of the pin on the rotating wheel in that direction). Thus a crank distorts the linear motion output so it is not purely sinusoidal. The shorter the connecting rod relative to the offset of the crank (i.e. the wheel radius) the more the distortion.
Why is the wheel made so thick? I noticed the thickness in other models as well.
To provide a good attachment for the pin, which would have a tendency to topple or bend a thin wheel.
Nice setup... Gives me some ideas for a project I'm brainstorming.
Amigo yo sigo tu canal en español jajajajaja cuando ví este video me sorprendió por qué dije, esa voz me parece demasiado familiar
*Awesome,Thank you* 👍👍👍👍
The motion of the piston here is exactly sinusoidal. Does anyone know how far off the motion would be from a sine with a tilting piston rod like all engines and compressors use? (well at least those that use a reciprocating piston)
Why don't you use for purpose?
E.g. you can make Air pump or something
Tjat will be nice
Nice and brilliant like
very nice video thanks sir
Manuel Rodriguez Achac in English? xD please share the blueprint of this proyect please
How to make this will you please explain
Very nice
cool, but what type of motor dc that you use? please i need that specification
It is just regular moter but its powered by power moter machine, also pls sub to my channel, i hope this help
Can i get this dimensions
I can see how it is great for rotary to linear motion, but how about the opposite (linear to rotary)?
It’s just a motor that goes one way because there is no motor driver so it can not go the other way
Like a reciprocating engine, it would require a flywheel for momentum so it wouldn't get stuck at top dead center or bottom dead center. Would also require initial rotary motion applied to the wheel when starting, as linear force applied when the rotating pin is at TDC or BDC would present a simple shear force on the pin and would not cause it to rotate. Alternatively, a second piston/cylinder arrangement in parallel operation but offset so both pistons are not at TDC or BDC at the same time.
Cool
Saudações LS Ludic Science. Saudações a todos. Mecanismos simples e curioso. Converte o movimento circular em linear no embolo. O oposto também é possível. Realmente interessante. Tudo de bom.
i want linear to rotational motion, not rotational to linear. linear must be driving the rotational output
Nice show other side allso like time of front side.
Price?
i've seen this before.
can u make a *steam engine*
I will try
thanks :D
Great
I need AM transmitter please ...
Nasirul Haque please I need the am transmitter components lists
👍👍
that's only HALF the mechanism.............. perhaps best to google before building
That is f*****g machine cheap.😊😊
So you made a Sybian.
👌👌👌👌👌👍👍👍👍
Dobra baza do wykonania pieprzącej maszyny...
First! and great mechanism
Your email pls ..
Look at her chooch!
wabs
Cool! - Cylinder was pronounced sye-LEEN-der but it should be SiLL-an-der.
