I liked the cement mixer and played with it as much as or more than I played with the other toy vehicles I owned. At some point‚ several weeks or months after Christmas‚ however‚ my biological parents led me to believe that it was a magic and/or highly unusual cement mixer. Probably my mother told me this in a moment of adult boredom or whimsy‚ and then my father came home from work and joined in‚ also in a whimsical way. The magic—which my mother likely reported to me from her vantage on our living

Trifilar Suspension Summary The polar moment of inertia for an assembly of solid objects was calculated using the trifilar suspension apparatus. The periodic time for the experimental and theoretical results were analysed and compared in order to study the relationship between the mass moment of inertia and the mass of an assembly.

Experiment Title: Torsion Vibration. Introduction : Torsion is the twisting of a metallic rod shaped object‚ when a torque is applied on two sides’ perpendicular to the radius of a uniform cross-sectional bar. Objective : Determining the natural frequency of a system undergoing tortional vibration. Theory : Using Newton’s second law of tortional system. ( [pic] …………………. ( Equation 1 ) where Io = mass moment of inertia of the disk Hence‚ [pic] ……..……

ello Doc Al and others. I am progressing along with my on-line basic physics course. I completed a new module and have some assessment questions to answer. Please review and let me know the ones that are correct. Those that are wrong just a little clue as to where my thinking process went a stray. I will add my thought process to the ones that I missed telling how I came up with the answer that I did. Thanks for taking the time to assist me on some basic questions. 1. What is the rotational speed

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches

Purpose To be able to understand and verify the relationship centripetal force‚ mass‚ velocity‚ and the radius of orbit for a body that is undergoing centripetal acceleration. Background Information An object moving in the same direction is not necessarily undergoing acceleration. If the object changes speed while moving in the same direction there is acceleration (or deceleration). On the other hand‚ if the object moves at a constant speed in the same direction‚ there is no acceleration
