Mechanical wonders – Le National
By MICHAEL JOHN UGLO
WELCOME aboard for the upcoming Mechanical and Technology Conference. People want to create moving objects and this can be wonderfully and captivating. Such a pursuit was the same in the ancient world as it is today. All this is looked at in mechanics and in technology is an application of this notion.
Mechanics is in principle the movement or movement observed in an object. This object is called a body and it can be a particle, a spaceship, part of a machine, a projectile, or anything that can be rigid, semi-rigid or fluid.
In mechanics, we are interested in the study of inertia, speed, acceleration and momentum. Everything is derived from an object to undergo movement as a result of an applied force which results in displacement which is the distance moved or displaced from its surroundings relative to the size or magnitude of the applied force.
Aristotle and Archimedes in ancient times brought to light the curiosity that gets entangled in mechanics. We had the English mathematician and physicist Isaac Newton who formulated the three laws of motion to lay the foundations of mechanics. Other equal pioneers had been Kepler and Galileo who also made significant contributions to this and to the field of science in general.
Applicability of technology and mechanics
In technology, we study in more depth the movement of particles and its application to other rigid and non-rigid bodies as well as to intermediate ones as semi-rigid bodies. This is calculated in kinematics as in motion and the forces known concurrently as dynamic as in classical physics.
Now, to our knowledge and at this point, classical physics based on Newtonian mechanics and the field of modern mechanics in quantum mechanics are acceptable to function as a unified body of knowledge. In this case, Newtonian mechanics is finite in scope and is considered to be part of the overall domain of quantum mechanics. The objects considered and the calculations carried out in Newtonian mechanics operate on a macro scale. This is an equivalent approximation in that so much time and calculations would have been done to do quantum calculations.
Thus, the above union factor has been considered the advanced field of quantum mechanics study at this modern stage. Two major contributors to these achievements were German physicist Max Planck and German-Jewish American Albert Einstein. It is the postulate on the calculation of particles giving rise respectively to Planck’s constant and to Einstein’s photoelectric effect that revolutionized the field of mechanics in physics.
The double factor of union is the theory of fields associated with mechanics. The field can be electromagnetic as well as gravitational. Therefore, any moving object can be a source of this field. It is therefore assumed that in quantum mechanics, the microscopic particles are the fields themselves.
This distinction really makes it more pronounced especially at the atomic level of mechanics. We see this discredit the degrees of freedom of particles with the application of the formula of the second law of motion in Newtonian mechanics. There is a factor called the Lorenz factor (λ) which applies when an object that controls a speed approaching the speed of moving light. It may be a projectile or a traveling agent of a missile guidance system or the like. The formula Force equals the mass multiplied by the acceleration (F = mxa) as given by Isaac Newton’s second law of motion is not true when the value of one (1) given to the Lorenz factor increases with increasing body speed.
So, the formula in this case for running efficiently is, the force is equal to lambda multiplied by the mass multiplied by the acceleration (and that is F = λ xmxa). This provides one of the foundations that goes beyond classical Newtonian mechanics at the atomic level.
In addition, quantum mechanics also gives effect in addition to the coexistence and continuum of the two models of mechanical studies to the fact that in the absence of any external resistive force such as air resistance, any object will fall said free. fall with a uniform acceleration fueled by the inertia (the object’s propensity to relentlessly move) of the object.
In elasticity, plasticity, electrodynamics along with thermodynamics and fluid dynamics, there is the inherent cohesion of particles and behavior which describe the mechanical behavior at the atomic level. It is also a superior achievement in quantum mechanics that stands out for surpassing classical mechanics in the field of mechanics.
The important take-home message for PNG is that we have a talent pool that is our people.
Mechanical trends in technology
Much of the field of engineering such as mechanics and civil engineering is based on Isaac Newtons’ laws of motion, according to Wikipedia. He also notes that in the natural sciences, mechanics is linked to thermodynamics.
In the example above, it can be seen that, an understanding of quantum mechanics in the wave motions of a single particle in the wave function as allowed by Schrödinger’s equations as well as matrix mechanics for l The finite dimensional state space for systems is the most desired unique. This will then give the mathematical and computational advantage essential to determine the permanent stature and lifespan of the engineering structure.
According to the World Encyclopedia, advanced applications of mechanical fields are mechanical engineering, construction engineering, materials science and engineering, civil engineering, aerospace engineering, chemical engineering, electrical engineering, engineering nuclear, structural engineering and bioengineering.
As previously mentioned and as Professor Marichamy asserts “mechanics is the study of bodies which are in motion or in a state of rest under the action of force”.
Emerging technological innovations
Again, according to Wikipedia, certain innovations in the field of mechanics play a very crucial role in capturing sunlight for use as a solar energy absorber. This was developed by Professor Ping Cheng from Shanghai Jiao Tong University in collaboration with Professor Zhuomin M Zang from Georgia Institute of Technology.
It has pyramid nanostructures that are made of bismuth telluride on a thin reagent to absorb incident solar radiation or the ray of sunlight that falls directly on it.
It is a perfect absorber that takes into account at nanoscale levels the wavelength of sunlight down to the nanoscale magnitudes that affect it. It is published on the Ennomotive titled Six Amazing Mechanical Engineering Innovations That Could Be Game-Changing In The Industry.
The important take-home message for PNG is that we have a talent pool that is our people. It is good that some of our world famous scientists and engineers are shaping this country so that PNG can develop using scientific, technical and technological innovations as a platform. There may be no other way.
Additionally, it is encouraging to see that our education department is focused on producing those innovators who could innovate and invent new artifacts and knowledge that may have commercial value to support this nation.
You have to remember it at the end of the day, it is not what you have that counts, but it is by what you give that you are remembered.
My prayer for PNG today is: God’s unconditional love unites people. Each is part of a body of Christ. No one should dictate and dominate anyone, but all will be participants.
