Wow ok now you're gonna trap me using centripetal force? I see how it is :/

Just finished reading your sephiroth prince fic it was really good!!

thank you!!! even if it’s only 2 chapters so far that one is actually a favorite of mine. i’m hoping to also continue it after i wrap things up with aitr

How To Use The Combination Of Electrospinning And Centrifugal Spinning Technology To Produce PC, Polycarbonate Nanofibers

The simultaneous use of electrostatic and centrifugal forces in the electrocentrifugal spinning process enhances the drawing force applied on the polymer jets during the fiber spinning. During electrocentrifugal spinning, a combination of centrifugal, electrostatic, gravitational, and auxiliary forces acts on the initial jet; if some of those forces are higher than the jet surface tension and viscous resistance, the jet is fully stretched out and spun into ultrafine fibers (Fig. 10.10). Because the electrostatic and centrifugal forces are combined in electrocentrifugal spinning, it enables the use of lower operating voltage and slower rotating speed compared with electrospinning and centrifugal spinning methods alone.

Applications of Newton’s Laws Description: The aim of the Exercise Package Applications of Newton’s Laws is to put into practice and further expand your knowledge of Newton’s laws across a wider range of applications.

The Exercise Package Applications of Newton’s Laws consists of the following:

*** 20 elaborate exercises that in 66 pages help you get more comfortable with the gravitational force, the centrifugal force and circular motion, kinetic and static friction forces, Kepler’s laws, drag forces, calculus and methods to solve integrals and differential equations, relative motion, Lagrange points, center of mass calculations, spring forces, tension forces, circular and elliptical orbital mechanics, multi-body systems, binary star systems, and vector calculations in one, two, and three spatial dimensions. All the exercises are original creations of the author;

*** Detailed figures and schematics, which are all entirely designed by the author, to provide visual support to the reader;

*** An explanation of the strategy of how to tackle the exercise;

*** A step-by-step guidance of not only how to formulate Newton’s Second Law in different types of situations and subsequently use that information to determine the motion of an object, but also how to numerically arrive at the final (or intermediary) result;

*** An explanation of the mathematical tools, in case they are required to solve the exercise. Preview: You can download here (free of charge) the first five problem statements to get an idea of the type of exercises that are included in the Exercise Package Applications of Newton’s Laws.

Intended Audience: Anyone who is deciding to start a degree in higher education that offers an introductory course in classical mechanics can benefit from the Exercise Package Applications of Newton’s Laws.

In 1965, A MACHINE WAS PATENTED TO DELIVER A BABY USING CENTRIFUGAL FORCE. THE DEVICE WOULD SPIN YOU UNTILL THE BABY CAME OUT, AND IT WOULD BE CAUGHT IN A NET

A machine that spins a woman in circles, using centrifugal force to aid in childbirth, was once proposed and was in talks for several years. The patent for medicine exists and can be found by searching the U.S Patent and Trademark office website. The patent for the so-called “Appartus for facilitating the birth of a child by Centrifugal Force” is under the name George and Charlotte Blonsky…

Difference between vacuum resistance and centrifugal force

When the direction of the force applied to a matter is different from the direction of motion of the matter, the force vector can be decomposed into components that are the same as and perpendicular to the direction of motion.

The space speed is increased by the same force component as the direction of motion or decreased by the force component opposite to the direction of motion. Vacuum resistance is generated by this linear force component.

The characteristic formula of vacuum resistance is as follows:

where γ is the Lorentz factor, m is mass and a is acceleration. The negative shows the opposite direction of force.

On the other hand, the direction of motion is changed by the force component perpendicular to the direction of motion. Centrifugal force is generated by this centripetal force component.

The characteristic formula of centrifugal force is expressed in the following formula.

The centripetal acceleration in Newton's laws of motion can be approximately expressed in the following formula.

where v is the linear speed along a curved path and r is its instantaneous radius.

The approximate relativistic centrifugal force is obtained by substituting the centripetal acceleration formula into the centrifugal force formula as follows:

where c is the speed of light.

As rotational speed approaches the speed of light, centrifugal force becomes infinitely large  because the Lorentz factor  becomes infinitely large.

The black hole at the center of the Milky Way galaxy rotates at a speed close to the speed of light and generates centrifugal forces to withstand its own gravity.

The magnitude of vacuum resistance is always equal to that of the same force component as the direction of motion. On the other hand, we can actively change the magnitude of centrifugal force by changing rotational speed.

Writing Process: Need to Pause. You need get off the ride, shake your head and breath, think about other things, step back, find what is working and what is not. Fewer conversations about assault and misery and things happening! That's a good plan. You must take a pause in writing. Otherwise it's just going straight ahead with half things trundled out, the ride getting faster, the wheels getting wonky, leaning to the side, one way and then the other, into an impossible turn which spins so tight that it becomes a centrifugal and nothing else.
