Well the point is that it doesn't decrease linearly whether the change in temperature is large or small, the change is non-linear.

Ice does not melt linearly. If you research about Newton's Law of Cooling you will find that the Temperature profile will be expressed below: T(t) = Ta + (To - Ta)*e^(-kt) where Ta= ambient temperature To= initial temperature k= thermal conductivity t= time So the e expression makes it...

As a Mechanical Engineer I would have to say yes you SHOULD go to college. To get an introduction into the science and theory behind your work you need to go to college to learn this skill as well as very good problem solving skills.

hmmm well this one may help with the electrical systems if you wanted to learn about that http://www.ecampus.com/advanced-automotive-electronic-systems/bk/9781111038144 and this might help you understand how to repair a car. I don't know if you were interested in that but knowing how to repair...

Agreed ^^^ with Tesla. He paved the way for a lot of breakthroughs. My personal favorite is Leonard Susskind. His work in physics is amazing. Here's a link. http://www.scientificamerican.com/article.cfm?id=bad-boy-of-physics

The only thing that comes to mind is by using SolidWorks. You could see if your school has this program available at your disposal because it costs quite a bit. You would first need to model extremely precisely getting all the dimensions, material selections, etc. correct. Then use the...

I second this. Get to work amrfd.

Again...weight has both magnitude AND direction. They measure your luggage using a weighing scale. These work by measuring the amount of displacement seen by the applied load using a spring system. Without a downward direction and magnitude how could there be any displacement? It would just be...

http://www.grc.nasa.gov/WWW/k-12/airplane/vectors.html or you can see here that even NASA says weight is a vector with both magnitude and direction and mass is a scalar. So to question NASA is pretty bold.

Muphrid and myself are correct. Weight is the resultant of mass being acted on by gravity. If you have ever taken the course(s) Statics or Physics or Dynamics, etc. you would know that weight is usually directed downward when viewing in a 2-D reference point. And downward means a sense of...

The best example I've found useful is the difference between mass and weight. Mass has no directional value only a magnitude which is a scalar. Weight on the other hand has a magnitude as well as a direction (downward) which is a vector.

The first link is just to learn about ICE's and the second book covers a lot more such as ignition systems, electrical systems, cooling systems, computer systems, brakes, manual transmissions, etc. Enjoy. https://www.amazon.com/dp/0768004950/?tag=pfamazon01-20...

@amrfd You will need to complete your FE license first if I am not mistaken. After you pass this 8 hour exam you can go on to get your PE. First you have to complete an "ethics quiz" mandated by your state board of engineers depending on your state of residence. Here's a link to help you out...

@ Travis King I wasn't considering cost because I understand that PVC is very inexpensive compared to other materials. Anything greater than 8 mm that would be not necessary. The OP wanted an exact number or range to go and purchase otherwise he/she wouldn't have posted and would have just went...

If you have a Mechanics of Solids/Mechanics of Materials book I would refer to them. The type of chapters in those books you are looking for is "Bending of Straight Beams" and "Bending of Flat Plates" or just general beam deflection/thickness theory. But from intuition alone, you are working...
