Explanation:
Engineering is science in practical terms. It is the application of scientific findings in problem solving and creating a better world.
How does technological advancements create more problems for engineers?
- Loss of job to automation: the world is driving at automating work processes through the use of specially designed and crafted machinery. Work is now properly being done using machines with little to no human input in the whole process. This is a huge let off for engineers. Engineers have to compete with machines which are their own inventions for jobs now.
- Fast paced work environment: machines can handle work more efficiently and faster than the people making them. There is an increasing race between engineers and their own inventions today for better product delivery. Unless a machine is faulty, they are more productive and efficient than man. This can cause engineers to want to catch up with their own inventions leading to a work life of stress.
- Environmental problems they cannot solve: most inventions use components from the environment. They release effluents that are very difficult to be properly disposed or stored. This is a huge problem for engineers and can lead to ethical calls from the government and the populace. In short, they can create problems they are expected to solve but cannot solve.
- Social problems: engineers can be portrayed as terrible beings for their own inventions. This leads to psychological problems on a good and creative invention. For example, rare earth metals in DR Congo are instrumental in making solar panels, but mining of these metals have forced several thousands of people into hard and intense labor on mines; there is a call on technological firms to stop exploiting people this way for their own gains.
- Misuse of technology: any good technology can be put into the wrong use. A nuclear reaction can be packaged into a bomb and also, it can be the center of electricity generation on a commercial scale. How can engineers solve this kind of problem? Technological inventions are subjective in their usage.

Answer: here you go sir
How trains work. On an electric locomotive, the wheels are moved by electric motors. ... On a diesel locomotive, a diesel engine drives the wheels via a mechanical transmission. Cutaway illustration of an electric power carHigh-speed trains are powered by electric current, collected from an overhead cable by a pantograph.
Explanation:
Chugging across short distances or entire continents, trains act as a major form of transportation worldwide. Also called railroads or railways, trains carry within their cars passengers or freight -- such as raw materials, supplies or finished goods -- and sometimes both.

Explanation:
In the first instance, you had a logic function, which you had derived using some sort of a truth table, then reduced it using K-maps, and finally derived the simplified logic. If you had used logic gates to implement the logic, the result would have been the fact that there were a lot of logic gates used. For example, for a function of 2 variables, we would need 4 AND gates and 1 OR gate. Thus, the resulting circuitry would have looked very complex.
Whereas, if you would use a microcontroller to implement the logic, all you need would be a piece of code to run the logic. There would either be minimum number of gates (or no gates at all, depending on the logic you wanted to implement).
Thus the microcontroller would make the circuit look a lot less complex. Making the design and texting simpler and since there are now fewer components to test. Microcontrollers is that on the same piece of silicon, you could embed a lot more complex logic or program, than using purely digital gates this is another good that comes with Microcontrollers.
