When I was in high school, I used go to school by bus, so everyday I used to wake up, get dressed up, take a breakfast and go to the bus stop. But I always hated wake up too early, so into the bus, as soon as I take a seat, I reclined my head on the window and took a little nap until I got at school. Once, on Monday, after a party in my friend’s house the day before, I went to school against my will, so in the bus I slept deeply and went with the bus till the terminal bus, I woke surprised with the driver poking my shoulder. I got ashamed and had to ask the driver to let me stay on the bus and go back all the way back again to my school, because I didn’t have money to pay another ticket so I had to ask for money to a girl who was next to me. I arrived late at my school, and had to explain to principal my case, he didn’t believe so much, but I entered in my class and saw the last hours of lessons. After that the principal called me and he said to me I had to call my father and asks him to go to high school. My father was angry; he didn’t believe my story because he thought it was a lie. The principal told me that I was punished for lying and I had to go to his office the next day to known my punishment. The next day I was nervous: I went to his office and he said to me that I made a mistake then my punishment would run around the court for an hour. I was in shock because I was never good at sports so I had to do it because the principal told me that if I refused, he would seek a more severe punishment. After that I went to the court for doing my punishment so the physical education teacher spoke with me and she said to me that the punishment set by the principal would be the note of this matter, I was more nervous to hear that because I didn’t want a bad grade so I ran fast but I get tired very quickly I ran for half an hour but I could no longer keep running because I was so tired then the teacher said I got 15. After that I knew I should never fall asleep on...

...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....
