Transcript: Control engineering Erik Alfredo Flores Guerra Control systems Undamped free movement 1 Hooke explanation Undamped free movement Case 0 In this spring, mass, shock absorber system, this system is free which tends to oscillate at different times after the sum of its forces is zero, this system has three forces and results in an equilibrium, the shock absorber force is the force of friction and the spring force is the force of stiffness, In this system we take into account the hook equations over damped movement 2 better known as second order systems, in this the damper is is decaying, the effect of the damper is what helps in this case and without this this system would be oscillating, in the equation we can find out if it is second order and there we can put the laplace transform, and we get a common factor in which to In the end the sum of all his forces will be zero. Explanation Critical damped movement 3 explanation Critical damped movement any decrease in damping generates an oscillatory movement, In this we use the critically damped differential equations of motion, in this the two roots are equal, the constant is equal to one in m1 and m2. This is equal to zero and is homogeneous, in this case the friction and stiffness is not so oscillatory when it is plotted. Under damped movement In this system, the damping in the spring and the friction in the shock absorber are more stable in a shorter period in which also by diferential equations and taking root without exceeding this will be the sum of their forces in mass to zero and in a time shorter is more stable in which it does not oscillate so much. example explanation forced system This system is known as a forced system since in the equations when substituting these give one as a result and they can be modified so that we want to obtain the result that we want as a product or a variable etc. example
Transcript: HOW aeroplanes helicopters Engineering aerospace machining Sean Osborne requirements Each customer has different requirements on how the part looks, tolerances and packaging What is my job? WHAT My job is to make parts for aeroplanes and helicopters using a lathe or mill. difference between each machine lathe and mill A lathe is a rotating spindle that clamps onto material with the attached chuck and the tool moves to the material. (3 axis) A mill is a rotating spindle that is attached to the tool and the spindle goes towards the table but only in one axis, while the table moves for the rest. (up to 5 axis generally) turn/mill special This is a machine that can do both turning and milling on a lathe style machine Tooling tools We make our own tooling like fixtures, jaws and clamps. location they are all stored on racks and correspond with a spreadsheet. materials I use anything from standard aluminum and steel to beryllium copper.

The, decide and create a series of questions that are to be asked during the game. 3. By hyper linking certain answers to different slides, the game jumps from slide to slide while playing the game. 4. This kind of setup is normally seen as a simple quiz show game.

Great with students, workers, family, etc. For example: With games like Jeopardy and Family Feud, players can pick practically any answers. The person who is running the game will have to have all of the answers in order to determine if players are correct or not. However, with a game like Who Wants to be a Millionaire, the players only have a choice between answers, A, B, C, or D. Therefore, when the player decides their answer, the person running the game clicks it, and the game will tell them whether they are right or wrong.
Transcript: Templates The key to generic programs a simple code! Output? Answer Namespaces Namespace is a feature added in C++ and not present in C. A namespace is a declarative region that provides a scope to the identifiers (names of the types, function, variables etc) inside it. Multiple namespace blocks with the same name are allowed. Templates Templates Templates are powerful features of C++ which allows you to write generic programs. In simple terms, you can create a single function or a class to work with different data types using templates. Advantages: Readability Flexibility Re-usability Function Template FUnction Templates A single function template can work with different data types at once but, a single normal function can only work with one set of data types. Normally, if you need to perform identical operations on two or more types of data, you use function overloading. However, a better approach would be to use function templates because you can perform the same task writing less and maintainable code. Example Sometimes, you need a class implementation that is same for all classes, only the data types used are different. Normally, you would need to create a different class for each data type OR create different member variables and functions within a single class. This will unnecessarily bloat your code base and will be hard to maintain, as a change is one class/function should be performed on all classes/functions. Class Template Class Templates Example virtual functions virtual functions Virtual functions ensure that the correct function is called for an object, regardless of the type of reference (or pointer) used for function call. They are mainly used to achieve Run-time polymorphism. The prototype of virtual functions should be same in base as well as derived class. They are always defined in base class and overridden in derived class. It is not mandatory for derived class to override Example Pass by reference Pass-by-reference means to pass the reference of an argument in the calling function to the corresponding formal parameter of the called function. The called function can modify the value of the argument by using its reference passed in. Does not copy the arguments. The formal parameter is an alias for the argument. References cannot be NULL.
