How Differential Gears Work (VIDEO)
The other day I was browsing the tubes and found something amazing. It was a video that explains how differentials work in cars. A differential is a device, usually but not necessarily employing gears, capable of transmitting torque and rotation through three shafts, almost always used in one of two ways: in one way, it [...]
Full StoryInfrared Controlled Autonomous Vehicle with video!
How cool would it be to have your own mini autonomous vehicle / drone that generates sounds like 3cp0?
Well that’s what I wanted to found out and so I built a 3cp0 mini brother. This gem has 2 modes, drone mode which is controlled by Air Conditioning Remote and autonomous mode. I will be updating this page more periodically. Hit the read button for more information. UPDATE VIDEO INSIDE!
Refrigeration Cycle Analysis
Abstract Refrigeration technologies have enabled great advances to the modern society. Contrary to what one might think the first civilizations that used some sort of technique to refrigerate a room go back to prehistoric times. On these ancient times ice was stored and packed with hay and other types of insulating materials in order to [...]
Full StoryHeat Exchanger Analysis
Abstract This experiment consists on taking measurements from a heat exchanger while varying the direction of the flow of the hot and cold fluids. Heat exchangers makes possible the use of machinery and processes that otherwise would generate too much heat to operate. The goals for this laboratory include determining the amount of heat dissipated [...]
Full StoryCooling Tower Analysis
Remarks As part of thermal lab some friends and I made an analysis of the cooling towers at the university used for air conditioning. This project was made by mechanical engineers: José M. Otaño, José R. Vázquez, Luis A. Plaza, Hiram González and me (Irvin De La Paz). Abstract A cooling tower is a series [...]
Full StoryMathCad: Hardy Cross
When sen. Stevens told *Internet is a series of tubes* he was wrong, but also maybe he was thinking of Mr. Hardy Cross. Hardy Cross was a structural engineer who devised a way (in the 1900s) to calculate flow rate of a pipe network when some pipe flows are known. I am sharing the technique with a mathcad subroutine and an example. Interesting technical stuff
Full StoryAthletic Prosthesis Analysis
Designing a prosthesis for walking taking into account the worst environment possible is common practice, but designing it for track and field is taking it to a whole new level. That is what this report is about, the analysis and design of prosthetic leg using toe flex technology (the one that our friends on the right uses). Beware this report is technical.
