Inertia

affect the rotational inertia due to the fact that angular moment is always conserved unless there is an external force. Angular momentum can include the rotating figure skater, my coach, and the point on the ice which is the toe pick of the ice skate’s blade. With the assumption that there is no friction on the ice, rotational inertia is a form of resistance during rotation in a counterclockwise direction. The skater’s body becomes the axis of rotation. Rotational inertia is also known as…

According Peter M. McGinnis (2013) the Newton’s first law is about the linear kinematic and is called law of Inertia. This law states that, ‘everybody continues in it states of rest, or of uniform motion in a straight line, unless is compelled to change that state by forces impressed upon it’ (McGinnis, 2013, p.88). Simpler, the law of Inertia says that if there is no external force acts on a subject, that subject will not move and it will remain in states of rest or if it was moving it will…

be used to calculate the angle of twist is a torsion load cell8,13. The load cell can be used to calculate the torque applied to the sample. From equation 1 below, the angle of twist can be calculated if the length of the sample, polar moment of inertia, shear modulus are known. Equation 1: Angle of…

Moment of Inertia for Rotating Objects Lab Report For this lab, the guiding question that needed to be answered was: For the system shown below, is there a functional relationship between the rotational inertia of the rotating object and the time required for the hanging mass to fall a known distance that can be determined experimentally? (as seen in Figure 1) Before beginning to attempt to answer the question, the lab had to be set up correctly. First, the rotating object was set tangent to…

second, which was the steel pipe. The small plastic pipe had the smallest inertia, which was 0.000003 and finished first. Also the small plastic pipe had the smallest rotational and kinetic energy compared to the rest of the pipes. The steel pipe had a inertia of 0.000008 and finished second. Then in third place was the small wood pipe with an inertia of 0.000012 and in fourth place the small copper pipe, also with an inertia of 0.000012. The pipe with the slowest…

sleep inertia; when the gradual process of waking up is forced or interrupted by an alarm, the worse the “grogginess” caused by sleep inertia feels. Sleep inertia affects one’s ability to perform simple tasks because the cortical regions in the brain, the part that helps humans make decisions, takes longer to activate. Functions such as “memory, reaction time, ability to perform basic mathematical tasks, and alertness and attention” are more difficult when one is experiencing sleep inertia. A…

Galileo Galilei was an Italian astronomer, physicist, engineer, philosopher, and mathematician, who made a great impact in modern science. He was born in Pisa on February 15, 1564 during the Renaissance era. Many mark the era of the Renaissance, as a time where modern science truly came to it’s peaking point. The Renaissance and Scientific Revolution were responsible for the introduction to some to science’s greatest modern theories. Galileo Galilei was known as the “father of modern science”…

This photo is of a Washington State Cheerleader performing a full basket. To perform this stunt, 3 bases interlock their arms while the top girl stands crouched down on their hands. The bases dip down and then throw the top girl as high as they can into the air in a straight line as the top girl stands up. She performs a stunt when she feels weightless at the top of the throw. In this photo, you can clearly see that she is twisting her body on two different axes, but I will only be talking about…

Diagram of Prototype A that consisted of an octagonal prism with a length of 11 in. or 27.94 cm. and height of 10.16 cm., while we created corrugated layers within the prism. We decided to change all the dimensions to centimeters instead of using inches as the units. Tinkercad model of Prototype B that consisted of a hexagonal prism with a length of 27.94 cm., height of 10.16 cm., and sides of the base of 4.445 cm. WIthin the hexagonal prism consisted of 6 equilateral triangles are connected…

problems and feels responsibility, then the chances for improvement are higher. So what are the barriers for the company for being not flexible to changes?! Now I want to mention inertia. As a company grows, it develops all kinds of engagements with its suppliers, its investments, and its own worldviews. Structural inertia is a symptom of success. Everything seems to go well so the company does not reevaluate the situation. Nokia worldview was that people needs a reliable, strong, high-quality…
