Moment of inertia

In this experiment, the two sets of data obtained from the same subjects were analyzed. First, the JNDs from the four subjects was pooled together and a repeated measures ANOVA analysis was performed. Then, Weber’s fractoin (JND/line length) was applied to the original data to compute the weber fraction and the same analysis test were performed. For this study, we were specifically interested on the data yielded from the Test of Within-Subjects Contrast and Effects and an ANOVA performed from…

Hypothetical Portfolio Our equally weighted portfolio includes Apple (AAPL), Whole Foods Market (WFM), Exxon Mobil (XOM), Citigroup (C), and Nordstrom (JWN). All of the companies chosen are paying dividends quarterly, and make up to 6.557% of S&P 500 as of today. From 2011 until today we see that our portfolio has had, return-wise, a similar performance to the S&P 500 with around 11% annual returns. Also, the correlation coefficient of 0.85 tells us that our portfolio is highly…

The purpose of the study, A Psychological Exploration of Engagement in Geek Culture, was to identify and understand why people participate in geek culture. Geek culture is defined as a subculture of enthusiasts that are interested in “obscure” media such as anime, sci-fi, and videogames. However, there are many faucets of the culture and it has become increasingly appealing to mainstream audiences, causing a greater shift in active engagement. Despite geek interests once being marginalized,…

Animal deaths, especially from anthropogenic causes, are valuable indicators of ecological and conservation problems that span a particular population (Collins 2011). Deer mortalities are no exception to this rule of thumb, as deer-vehicle collisions (DVCs) are a growing problem in the US and reflect the displacement of deer populations. Over 1 million DVCs occur in the US annually and result in the loss of human life, human injury, and considerable financial costs resulting from the vehicle…

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…

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…

When rebuilding the Villa, the out of -plane inertia forces should be the focus to be prevented and separated. Also, the beams are assumed to function as members of moment frames because of the size constraint of columns, which is relatively small compared to most common cases in buildings. It is an important step to access the diaphragm adequacy when designing…

water, and by reading the spins in wire shows the ratio of gold to silver. To conclude Galileo Galilei helped pave the way for modern physics during the Renaissance period with his vast knowledge and theories. During his lifetime, he came up with inertia, friction, acceleration, hydrostatic balance, and displacement. Each and every one of these discoveries have helped revolutionize physics, advancing theories and ways of…

track of the roller coaster keeps the car and therefore the rider, from travelling in a straight path. The force of a rider's acceleration pushes them from the coaster-car floor, and their inertia pushes them into the car floor. As one travels upside down on the loop, he or she's own outward inertia creates a false sense of gravity that stays fixed at the bottom of the car. Thus in most loop-the-loops,…
