Engineering Questions

Question 1

Cut the blades - the tube allows blade to cut 5x2. Use a PVC pipe on a flat surface and cut rectangular strips equal. Between opposite ends cut diagonally leaving 30mm to the vertex. Check the curvature of future generator blades.

The angle of attack (leading) edge should be rounded so as to provide less air resistance, the angle of departure (tailing) edge wants to be sharp so that air can escape without difficulty (Babu & Mohanty, 2010). Sharp edges should be removed. The engine is bolted to the core support and fixed on the support tube, it is important that the motor shaft is perfectly balanced elation ace spades. The principle of the generator is simple: the propeller moves the alternator, which charges the battery (and keep), which in turn feeds the converter and there we have our output 127V! It is enough to power televisions, energy saving lamps, radios and so on.

Question 2

From the beginning, the man had the need to develop new technologies such as spears, knives., In order to meet basic needs for survival (food, clothing) once stabilized achievement began to think and develop technologies that improve their quality of life, but also developing technologies to harm their peers and subject as being the war machine among others. The engineering is a profession that generated more impact in society and for better or for worse, most appliances and transport we use every day are due in large part to a model designed by engineers with the objective of meet different kinds of needs in the best way possible (Franquesa, Cruz, Álvarez, Sánchez, Fernández & López, 2010). In turn this is also the result of years of accumulation of knowledge developed by different people. Just as engineering knowledge allowed the development of many practical things also were responsible for the development of disruptive technologies for society.

All these technological changes have produced a revolution in the way we live and think modern man's life today is more rapid, the extreme rapidity of technological advance makes what you buy today tomorrow either obsolete, leading to constant consumerism in some people and causes serious health problems (Li, 2011). Today technological progress is very shocking, seeing an object heavier than air flying like airplanes, traveling to distant planets, see how we can so quickly and easily communicate with someone who is anywhere in the world, getting any kind ...
