The Defining Moment

caused mainly by material choice and cross-sectional area. It is clearly shown that material changes the slope of the curve based on the three rectangular beams. All three have approximately the same cross-sectional area and approximately the same area moment of inertia, so the only variable that is changing is the material. This is significant because it shows that material choice has a large…

that could 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…

M is the resultant internal bending moment calculated about the neutral axis of the cross section, y in this case is the thickness of the beam divided by two, and I is the moment of inertia of the cross-sectional area about the neutral axis [4]. The final equation is, Equation 5 is utilized to calculate the deflection δ of the cantilevered beam at x = L when…

nearly nine thousand people died from the two earthquakes in April and May 2015, and the remote villages had many homes destroyed from the quakes (Bhandari and Najar). Around noon local time, the first major earthquake hit Nepal, which registered a moment magnitude of 7.8 (Rafferty). Both countries, Haiti and Nepal were in dire need of aid relief. Richard…

In this week’s reflection assignment the required reading was over restoring rifle and shotgun barrels. The article explained the processes and procedures for lapping shotgun and rifle barrels.as well as altering shotgun barrels. And soldering, brazing, and welding In the required reading the author explained the differences between lapping the different lapping compounds. And explained the applications for the different compounds. The article also gave an overview of the tool involved in the…

chart, there was a positive correlation between the years of high school completed and the income of the respondent. The more years of high school that were completed led to a higher income for the respondent. This was calculated by a Pearson product-moment correlation coefficient. The values that were found were positive with r=0.208, n=906, p=0.000. This is summarized by the scatterplot above. The Sig value strengthens the argument for a positive correlation between years and school and a…

To determine if mood state changed from pretest to posttest a paired samples t-test was calculated on mood state. Mood state changed from pretest (M=27.7, SD=5.8), to posttest (M=30.1, SD=4.8), t (43) = -4.8, p = 0.00. To test the hypothesis that HAI increases mood, a one way ANOVA was calculated. As displayed in table 1, the effects of conditions had no significant difference on mood in people, F (2, 42) = 1.5, p = 0.23. To test the effect of species, a 2 (species) x 3 (condition) factorial…

Introduction: The purpose of this study is to see if there is a link between the birth weight and gestation of newborn babies with smoking mothers and non- smoking mothers. The significance of this investigation is to find a relationship between the two as it might help with health benefits. The features in the investigation are the relationship between the two sets of data between the birth weight and the gestation period of smoking mothers and non-smoking mothers. Part A: The median for the…

Summary The paper “Observant, nonaggressive temperament predicts theory-of-mind development” by Wellman, Lane, LaBounty, and Olson (2011) reports on their longitudinal study, that was run to test the connections between a child’s temperament and their development of a theory-of-mind. Temperament is a multi-layer concept that influence a child’s personality, which influences how they interact with the world. The way that children interact with society and the way society interacts with the child…

However, even though this is the population from which a sample was taken for the research, it may be assumed that ultimately the goal of the study is to define the population as all workers in Taiwan, for purposes of extrapolation of the data. Additionally, only respondents holding a full-time job were selected for the analysis in order to highlight the potential effects of work/family conflict (Lu et al., 2011). Description of Data and Descriptive Statistics A wide variety of data was…
