Contest: Best LPG graphic or video!

Hey LPG Fans, THANKS.  Over 100 dedicated builders are out there.  It’s neck and neck.  Each month more and more view this page.

 

Send a still photo, video, or JPG graphic and have it posted here with your link!  www.william.mostovoy@mostosoft.com.  All submissions may have your consent to post on www.mostosoft.com. Videos should be under 10Mb.  If you have a site or blog include it for placement of a link here.  We can make beautiful music together.

 

Life is grand LPG fans.  Two wheel design video. Or Cartoon Video

Da Vinci is the origin of Linear Propulsion Gear Cars.  Note the key is the OFF CENTER POST.  The loose fitting post makes good sense.

With Minor Rotator and Turbocoil:  New Video Link of it going! It’s a Sky Drive

Perhaps a Retro-Looking body would suit the application

 For those building at home.  Mr. M. has crafted one out of spare parts.

It really works, See it go at <Play the video>

OK now we see our parts for  LPG.

 

Note that the electric motor has a gear on it.  This is not direct drive.  This is a better option.  Mechanical advantage kicks in on geared things.

 

 

 

 

 

 

 

The Mona Lisa portrait showed the essence of both the subject and the painter Leonardo DaVinci.  DaVinci worked 500 years ago and created detailed designs of mechanical objects of his day.  From War tools such as the Catapult, to Lens Grinding tools to many other theoretical machines like the Air Screw that give the idea of a helicopter, they clearly showed how engineering designs would look from that point forward.

 

An exhibit is touring the U.S.A. and is currently at The Water Tower mall in Chicago entitled DaVinci machines.  The curators have commissioned construction of many of the drawings of Leonardo.  $15.00 adults, $12 Students.  Searching the web you can find some video of the exhibit.  (Google: DaVinci ABC7Chicago.com).

 

One idea the Rotational to Linear motion machine shows a machine with the off center post idea!  Was that DaVinci or an over and back attribution, we may never know but the exhibit truly impresses the engineer of any era.

 

So for the kids the post of 7-24-2016 was to inspire a 5 step assignement in Linear to Rotational motion.

1)      Cut out a cut sheet

2)      Prove the up and down linear motion produces a rotation.  (Seeing the exhibit or exhibit video would help)

3)      Create an animation of the mechanism

4)      Create a physical model of the mechanism

5)      Show in a video animation of the mechanism driving a cart

Promise of tomorrow.

6)      ENVISION or Do create 2 Linear Propulsion Carts and race them

7)      Using foot pump orbital centripetal and a play pedal animate a car going with it

8)      Create a working concept car that goes with the Play Pedal and Foot Pump Orbital Centripital

9)      (**MrMostoman YouTube Channel has the animation of many of these ideas)

Thanks everyone and hope you get those DaVinci books, visit the exhibit and do some of the project.

If any of you have a special artistic person or teacher, the assignment is to duplicate the LPG video of your choice.  The quadricycle has been viewed over 300 times.  (Practically gone viral in Bill world)  This is the “Cut Sheet”   please boys and girls moms and dads print out the cut sheet and create your LPG Quadricycle videos.  Remember simple video rules, the time of a video is key 15 sec, 30 sec or 60 sec or 90 sec.   The Mechanism has origins in Leonardo Da Vinci’s work over 500 years ago.  Internet searching on Da Vinci machines may get you started.

 

Here is that cut sheet.  (Mouse over use the Right Mouse button and print.

 

 

 

MS Windows trick, Left mouse button over image <save> or <print>

 

At home project before materials.  Apologies.  Box cardboard not advised.  Did not have mini carriage bolts.     To show in ways out ways.

 

 

Assignment: For Middle School (*with help) High School and College

If your spindle gear rotates 3 times per second and you have a rear gear connected in a 1 to 1 ratio with a wheel of 24” (60cm Diameter)

What speed would the bike or cart be traveling.  Then figure out the 1:2 and 2:1 ratio answers.

 

Remember if a diameter of D, C=Pi * D C is the circumference or distance covered in one rotation.

 

1:1  3 rotations * 1 sec =  3 C/s * 60*3s/1min* 60Min/hr = 648000cm/hr  *1m/100cm = 6480 m/hr = 6.48kph

 

The advantage of gearing can be proven.  Think of the 10 speed cycles available on bikes..

 

 

There is online help called http://www.bikecalc.com/  Cadence is RPM go ahead and fiddle with it.  Rim sizes are limited.   So first set your target speed 30mph then your cadence 180 (RPM) then note the gear it would have you in say 46:11 about 4:1

 

Kids be careful.  They would be fun to race

 

 

 

 

You could calculate the speed on an unloaded test machine
