Modular enclosed and elevated roadways for bicycles. - Structural Engineering Freelance Job

Posted by Cool_Tubes

If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting!

First, please visit our website at WaterCooler.cc

You will see our Water Cooler roadways which are enclosed, elevated roadways for bicycles.

Go to “technical details” page for more illustrations.
Go to “Patent Excerpts” and download the patent and the patent drawings which are .pdf files

This should give you a good idea of the intended design.

We need a structural analysis of two components.

1. Within the side walls of the roadway are Cold Steel Formed trusses. We have about 4ft height inside the walls which enclose the trusses. There is a truss on each side. We need to determine the truss specifications and we need to know the maximum span we could have between the external support hangers (shown as arches in most illustrations). In other words, we want to determine the longest realistic span using conventional CSF truss fabrication methods and materials.

2. The illustrations show arch supports and hangers which hang the roadway modules from the arches. The arches could be CFS assemblies such as
curved trusses, pipe or bent steel. We need to use conventional, low cost, easy to procure materials (no exotics like carbon fiber, etc. no plastics). We
need the anticipated loading on these trusses and, assuming they are fabricated from steel pipe, we need to know the specs: Wall thickness and diameter.

If standard size pipe could not be used, we need to consider curved trusses.

We will assume the arch span to be 36 ft (to span a typical two-lane road) and the arch height at the center point to be 30ft, 36ft and 40ft. This
means the “arch” may or may not be eliptical in shape. The roadway modules hang from these arches at or near the peak (the highest point), but
we would like to be able to hand two or even three roadway sections as show in some of the patent drawings.

The roadways have a uniform static load of 40 lb/sq ft with bikes, but a much larger load if filled with pedestrians. Assume they are 18 ft wide meaning the MINIMUM static load is 720 lb per linear foot. We need
the span (problem 1) to calculate the total load per arch. Of course, we need to add reasonable loading for the structure weight, snow and wind loads. We also need reasonable safety factor.

3. We also need to consider the “topple over” effect due to horizontal wind load. With the arch base points 36ft apart, and the horizontal wind force
at the peak (to ft high), what will the tension force be trying to lift the one leg out of its footer?

There are, of course, other issues. But, please quote on determining the above issues for phase I. You may quote on a per hour basis and you initial guess as to how many hours you would expect. This way, we would pay for any additional time you used.

Riding in the Cool Tubes - 3D Animation Freelance Job

Posted by Cool_Tubes

First, please visit our website at WaterCooler.cc

You will see our Water Cooler roadways which are enclosed, elevated roadways for bicycles.

We need an animation showing teens, young adults, business people and a senior citizen riding bikes, Segways or electric scooters through
our roadways.

The animations would be on our website (flash, I guess) and we want a “blockbuster film” to post on UTube.

Ideally, there would be 4 or so scenes - 1 with teens riding and having fun, 1 showing a morning commute to work, 1 with mom and child going shopping,
1 senior couple taking a romantic ride.

Currently the photos you see on the website are autocad 3d renderings.

We are not knowledgable in animation, your terminology or exactly what you would need.

We could render images of the “Cool Tubes” and we could get you a “walk through” animation from autocad.
We do not have great backgrounds.
We do not have sound, but would like appropriate sound for each scene
We do not have characters other than some (not very great) photos.
Animated characters would probably be better.

Kids Art Camp - Poster Design Freelance Job

Posted by The Bella Project

I am looking for a poster to advertise a Kids Art Camp that will be over the summer. I would like a very modern look to it and not a “crayola crayons.” The camp is all about creativity and artistic design so I would like the poster to reflect those values.
