two sides’ perpendicular to the radius of a uniform cross-sectional bar. To study the response of materials under a torsional force‚ the torsion test is performed by mounting the specimen onto a torsion testing machine‚ then applying the twisting moment till failure. The torque and degree of rotation are measured and plotted. It can be seen higher torsion force is required at higher degree of rotation. Normally the test specimens used are of a cylindrical rod type since the stress distribution across

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

Unfortunately‚ I don’t know any of these people personally‚ so I would have to be broad and unspecific when describing them. I know that we have all read the same material‚ so we have that. I hope that my audience‚ especially my professor‚ has experience with poetry. Whether that is from taking English

Analytical Essay on Drama Trifles by Susan Glaspell Heidi Barnard South University Trifles’ By Susan Glaspell I believe had several small defining moments leading to the one larger defining moment‚ which brings together all of them together. The defining moment is the discovery of the dead bird hidden in the pretty red box‚ this leads back to smaller points such as her sewing and the bird cage. “ Here’s some red. I expect this has got sewing things in it. (Brings out a fancy box.) What a

The system can therefore be described by the following equation (θ ) ̈+ g/r sin Θ = 0 To achieve the backward giant circle energy lost to frictional forces and the conversion of energy must be overcome.

I wake up surrounded by suffocating darkness‚ gasping for a breath that won’t come‚ my heart pounding. I don’t know what time it is and for a minute I don’t know where I am‚ I’m still trapped in whatever hellscape I was in. It takes me another minute to realise that I am home in my bed‚ and another minute to calm my racing heart and even out my breathing. In and out‚ in and out‚ over and over again until I’ve calmed down. At this point I’m too exhausted to go to find my parents so I settle for trying
