Rotation

angular momentum during counterclockwise rotational spins. A figure skater is trained to use a double axel, a jump with forward takeoff, with a split jump to create a parabolic leap in the air. A double axel contains an additional rotation in the air due to the forward takeoff. Assuming that there is no friction on the ice and no resistance in the air, every figure skater must be concerned about his maximum height, horizontal and vertical displacement and the speed required to perform a perfect jump with a double axel. A figure skater’s trajectory can be determined by the initial takeoff angle of the ice skate’s blade, initial velocity, and the initial height of the takeoff. The peak of the figure skater’s vertical displacement is also known as the figure skater’s maximum value due…

serves as the outer steel walls to contain the shock wave, while at the same time providing a structure and frame for the slats and rods (which externally support the weight system). The rods that rotate with the slats also interface with the weight system which provides an opposing moment to resist rotation in order to delay the travel of the shock wave. Lastly, the shell serves as a structure to fasten the flow straighteners inside the posterior section of the device. The manufacturing of each…

Each powder mixture has unique characteristics, and so have a unique optimization curve to achieve an acceptable state of uniformity and particle size distribution. Many blending units are available which offer differing shear, convective and dispersion properties on the powder bed. Convective forces refer to large groups of particles moving in an orthogonal direction to the axis of rotation. Dispersion is random motion of particles due to collisions, usually parallel to the axis of rotation,…

recline, the apparatus resolved to utilizing a motor to drive rotation of a screw via a coupler, on which, a capture nut would be moved laterally. The capture nut was secured inside the lower rear arm bracket of the scissor mechanism, and movement of the nut was expected to provide the necessary lateral displacement to cause the struts to fold or expand and raise or lower the platform. The backrest was connected to the legrest via a lever-like connector beam where rotation of one of the rests…

The difference between the movies, The Core and The Martian, would be the logic of scientific principles and ideas. The Core is a movie; where a team tries to drill to the center of the Earth, so that they can restart the rotation of the Earth by blasting the Earth’s core with nuclear missiles. The movie, The Core, had flaws and errors; in which, causes unrealistic standards for science and unjustified the idea of what would really happen in this kind of situation. The main struggle the team…

mercury in whic hthe rotation of mercury in a highly charged electrostatic tube leads to an antigravitational field as well. So thus Serum 525 is put into these counter-rotating cylinders, and they're spun up to high speed in opposite directions and what this is going to do, just to explain a bit of the physics for a moment, it's going to cohere the rotaton of the atoms, and molecules of this substance on one plane. So in other words, it's going to align the axis of rotation of there things.…

Specific unbalance: □(→┬e=(m□(→┬r ))/M) Figure 2.1: The detail drawing of the theory of the static balance. For the static unbalance rotor, no matter how many eccentric mass, just needed to keep single-plane balance. Dynamic balance The mass of static unbalance rotor could not be considered it is distributed perpendicular to its axis of rotation in the same plane. When the rotor rotating, due to the centrifugal force caused by each eccentric mass are not on the same plane,…

or more nuts, and opposites when there are only four. To place the cap back, (if there is one), line up the design from the cap to the design on the tire and tap it on gently, but with force. Make sure that it will not fall off. This technique is a basic part of vehicle ownership as well as taking care of your vehicle. Vehicles can be taken to an auto repair shop and done professionally but knowing how to this by hand can save money and time. Repair shops may often have people in line and then…

Soccer is a sport that involves two teams of 11 players who strike a football with their feet. When the players kick the ball they can affects the way the ball spins in the air. Factors that affect the way a ball spins include: wind drag, the way the ball is struck, and friction. These affect it due to the change of the air-flow over the ball, which occur when the ball spins in both a translational and rotational motion. This is due to the magnus effect and bernoulli principle occurring when the…

Wall-e is a new, dare say one of the best upcoming roller coasters and it is based off of the sensational movie Wall-e made by Disney’s Pixar! In the movie, the plot takes place in 2805 where humans have abandoned Earth on the account of it was not in the ideal shape for humankind to survive in. Therefore, humans left robots to clean up the mess they had made where after some time, the Earth became habitable once more. Mankind had been sending extraterrestrial vegetation evaluators or EVE to…
