The day of the oral report is the most embarrassing moment happened. I slowly raise my hand after the teacher asks if anyone else needs to do the oral. As I scoot the chair back to stand up, my ears begin to turn red hot and I start to sweat on my hands and forehead. As I look up from the podium, I am startled by the forty pairs of unwavering eyes glaring at me, waiting to be engrossed by my brilliance. I find myself having difficulty breathing, almost as if I have forgotten how to. I wipe the sweat off my brow, grab my index cards tightly, and open my mouth to speak. But the words just will not come out as I hit a stuttering block. Those same forty pairs of eyes are gazing at me in wonderment. I avoid their scowls by looking down at my index cards, held by my excessively sweaty hands. The class is remarkably silent, waiting for me to continue. Nervously, I attempt to speak again, but again I block. I make a stronger effort to try to spit the words out. I first realized I was different than the other students in my class during the fifth grade. While the thirty-four other students in my class could speak aloud in class without any trouble, I was not as fortunate. I noticed that sometimes when I spoke, I would suddenly get stuck on a word that I could not say. During my middle school days, I became shy because trying to hide this quirk of mine was my main concern. The childhood teasing proved to be a traumatic experience. So much so, that if I could avoid speaking aloud in class, I would. I did not want to subject myself to a class full of students laughing at me. I was so upset at my lack of fluency in speech that I thought something was seriously wrong with me. I remember thinking that if I was ever granted one wish, I would not wish to be the richest person in the world or to be the smartest person in the world, but rather I knew with clarity that I would wish I could speak clearly, without any stuttering problem. But no matter how much I wished, it did not...

...Sadie D. Hood Lab 8: Moment of Inertia Partner: Florence Doval Due 16 November 2011 Aims: To use a centripetal force apparatus to calculate the moment of inertia of rotating weights, using theories derived from ideas of energy transfer (Im = MR2 (g/2h)(t2-t02)) and point mass appoximation (m1r12 + m2r22). Set Up
Procedure First we measured the weights of two masses and wingnuts that secure them. Then we placed one of the masses on the very end of a horizontal...

...Moment of Inertia
1. Abstract
The goal of this study is to understand the transfer of potential energy to kinetic energy of rotation and kinetic energy of translation. The moment of inertia of the cross arm my group measured with the conservation of energy equation is: 0.01044 kg/m2 (with the mass of 15g), 0.01055 kg/m2 (with the mass of 30g), which is kind of similar to the standard magnitude of the moment of inertia of the cross arm: 0.0095...

...[pic] The flywheel of an engine has moment of inertia 2.5 kg•m2 about its rotation axis. What constant torque is required to bring it up to an angular speed of 400 rev/min in 8s, starting from at rest?
[pic] A solid, uniform cylinder with mass 8.25kg and diameter 15cm is spinning at 200 rpm on a thin, frictionless axle that stop the cylinder axis. You design a simple friction brake to stop the cylinder by pressing the brake against the outer rim with a normal force. The...

...Title: Mass Moment of Inertia
Objective:
To determine mass moment of inertia of a part using experimental method.
Theory:
If a part has been designed and built, its mass moment of inertia can be determined approximately by a simple experiment. This requires that the part be swung about any axis (other than one that passes through its CG) parallel to that about which the moment is sought and its period of pendular oscillation...

...THE MOMENTS OF A RANDOM VARIABLE
Definition: Let X be a rv with the range space Rx and let c be any known constant. Then the kth moment of X about the constant c is defined as
Mk (X) = E[ (X c)k ]. (12)
In the field of statistics only 2 values of c are of interest: c = 0 and c = . Moments about c = 0 are called origin moments and are denoted by k, i.e., k = E(Xk ), where...

Abstract
The moment of inertia of a complex system was determined through two different approaches. A string was tied to and tightly wound around a horizontal disc and then strung over a vertical pulley where the other end was then tied to a hanging weight. Underneath and attached through the...

...Introduction
A bending moment is simply defined as “the algebraic sum of the moments of all the forces which induces bending of an element” (1). The aim of this assignment is to work out the bending moment in a simply supported beam when different concentrated loads are applied to it. A simply supported beam is a structure, usually with a straight profile supported at the ends, often pinned on one side and simply supported or on a roller on the...

1.1 Summary
That performed laboratory session on bending moments and shear forces requires good understanding and sufficient knowledge of axial forces. Bending is defined as a behavior of any structural element that undergoes the external load, which is applied perpendicularly to longitudinal axis....
