Determination of principle stress - Lab Report Example Likewise, the value of normal stress be maximum in another plane. This plane is known as the minimum principle plane or principal plane. The normal stress on the minimum principle plane is referred to as the principle stress (minimum principle stress). Mohr’s circle is graphical technique used to find principle strains and stresses in materials. It also indicates the orientations or principle angles of the principal stresses. This experiment focused on using Mohr’s strain circle to determine the principle directions, principle strains, and maximum strain. The wheat stone bridge for the different channels was set at zero. The torsion rig was loaded with different masses. The masses were used to record the gauge strain readings at different loading levels. The necessary measurements were taken and recorded. From the given experimental readings the Mohr’s circle was drawn and the principle strain, principal direction, and maximum strain determined. The corresponding principle stresses were calculated together with the maximum shear stress through the application of the generalized Hooke’s law. The torsion theory was used in determining the shear stress that acts at the outer radius of the principle stresses and the cross section. Provided the stress componentsï€  Ã¯  ³x, ï  ³y, and ï  ´xy, it was possible to determine the principle stressesï€  Ã¯  ³1, maximum shear stress ï  ´max, the principle angle ï  ±p, and angle ï  ±s. In this regard, the maximum normal stress was found to be 52.5 MPa, minimum normal stress was found to be -18.5 MPa, principle angle 34.2 degrees, Maximum shear stress was 35.5 MPa, Maximum shear angle 10.8 degrees, and angle was 79.2 degrees. The Obtained results show that the shear stress is positive and the normal stress is equally positive. This means that the normal stress is position outside the action plane and the shear stress is rotated clockwise in the point to be considered. Normal stress involves the stress that happens when axial

Describe a place or environment where you are perfectly content. What do you do or experience there and why is it meaningful you - Personal Statement Example Its satisfies all the five senses: It has this serenity that is exclusive, the air being inhaled is purified as there are little or no sources of pollution, the wind that blows is gentle, the sound of the animals brings a feeling that one can get from no other place, and the taste of the wild fruits provides nature’s best, as compared to the fruits that reach the markets that have be grown using chemicals. The sense of nature being around me in its purest form brings a sense of peace. Being in the woods gives me the peace that I cannot get in an environment that is characterised by the hooting of vehicles and moving machines and the threat of being mugged or knocked down by vehicle. It also takes me away from thinking about unfinished businesses and many of life’s worries. The woods present me with an opportunity to hike, making me reconnect with nature in the best way that the earth we live in provides. This is also an opportunity to go biking and feel the adrenaline as the air rushes past me and the earth moves fast behind on a a rough terrain that ignites my endurance. The wooded environment is also good for hunting, which makes me be in touch with other forms of life such as birds of different types, rodent, snakes, and lizards among other animals. Watching animals in the wild is for me one of the greatest wonders that this world presents. Seeing how the eagle preys on the rodents from the moment it targets its prey to the time it catches it is simply amazing. This makes me appreciate nature that no form of human invention can be of that complexity. Seeing how the ecosystem balances itself reminds me that there is an important part that I was created to do on earth. As every part of the ecosystem has and fulfils its purpose, so do I have a purpose that I am to fulfil. My recent visit to the Grand Canyon was an experience of a lifetime - one that I would not want to wash away from my memory. The place is such a
