Has China finally figured out how to beat the USA?
China is a very smart country. They understand they can not possibly go up against the west militarily, but they sure as hell can bury us economically. Militarily, outcomes are very hard to predict. There is way too much chaos. Economy is far easier to predict and manage. China, after 5,000 years of learning from the past and that war is really a last resort, that diplomacy and economics are the only way to go. China has also stated they will not launch a first strike against any sovereign nation. The USA has not said any such thing. Proof is in our wars now. As far as Mandarin. I'm an ex pat from the USA living and teaching English in China. I assure you beyond a shadow of a doubt that you will not need to learn Mandarin. It is one of the most difficult language to learn where the tones must be 95% correct to be understood. Westerners can spend years learning it and still suck at it. English is far easier to learn and is also the universal language used in international business and government. The Chinese government knows this and that is why 300 million people in China are learning English. Peace Jim .
What is something electrical engineers know that others don't?
Ever wondered why only 50 Hz frequency is accepted in India,or the cup like thing on transmission towers which holds the transmission wires..Or the best thing even asked in a movie How does an Induction motor starts???Then being an Electrical Engineer I feel privileged to take you all in the cosmos of electricity…1)50 Hz frequency is accepted in India due to lamp flickering effect which occurs at low frequencies like 20 Hz or so(called stroboscopic effect).2)The cup like thing which holds the transmission lines is the insulator which is made up of Porcelain (chocolate colour) .And Hence higher the voltage, higher will be the number of insulators required.3)Now comes How does an induction motor starts??When we three phase supply to three phase windings balanced in space and in time then a rotating magnetic field is created of constant magnitude in the direction of that phase which carries the maximum current at that instant…(This is the definition we are supplied with during our graduation) ..But I make that simple for u….First of all we have stator (stationary part) and rotor(rotating part) and core where all the flux cutting operation takes place.Now when u supply stator with three phase supply a magnetic field sets up and this cuts the stationary rotor conductors.And according to Faraday’s law when flux cutting action is there we have emf induced in rotor conductors and as they are closed(short circuited in electrical terms) current flows which also creates its own flux.Thus the interaction of these two fluxes creates a torque which rotate the rotor.And that’s how an Induction starts…(Vrooooooom…)4)Another fact can be what inside of fan regulator which all use everyday?It is TRIAC…..It is a power-electronic device which changes the firing angle to get different voltage and that’s how we control our fan….The Figure under induction motor is Single phase Induction motor which we use in Fans and Water motors.List is endless……..Will write many thing more………
