Fracture mechanics

Literature demonstrates that pitch types (fastball, curveball, change-up, slider) generally have similar kinematics with only minor differences in forearm and wrist action, and even less so in the elbow and shoulder(36-40). Fleisig et al demonstrated in a kinematic study involving 21 collegiate baseball pitchers that the change-up pitch is the least stressful, while the curveball and fastball have similar elbow and shoulder kinetics, with the curveball exhibiting increased forearm supination and…

Albert Einstein and Isaac Newton, both intelligent, driven, revolutionary scientists who changed the way we look at the world. Their advancements science can still be felt in our everyday lives. Both Newton and Einstein made equal contributions to modern physics and mathematics, with Einstein building upon Newton’s theories, impacting the world today. Isaac Newton, born December 25th 1642 (January 4th 1643 depending on the calendar) in Woolsthorpe in Lincolnshire England. He was the only son…

REVIEW Name Course Date of submission Introduction Meliva Marić was a Serbian scientist married to Albert Einstein. Marić was a very intelligent woman, and she studied physics and mathematics at the Zurich Polytechnic where she met Albert Einstein. There has been lots of conspiracy surrounding her role in the life of Albert Einstein, the scientist who invented the relativity theory. There have existed a lot of theories about her involvement in the works of Einstein. In the…

Isaac Newton Sir, Isaac Newton Is a large figure in the history of science mostly for his laws of science but what about his contribution to the enlightenment. Isaac Newton developed and contributed in huge ways that play a very big factor in the Enlightenment and in the way we comprehend the world today. Sir Isaac Is responsible for the creation of calculus which is a big brand of mathematics, this is still largely used in the world today. Also his most famous contributions were his…

Aim: To investigate the changes of velocity and to investigate the acceleration and of the car. Also to investigate to see if the velocity and the angle of the wooden plank would make the severity of the crash increase. Hypothesis: The higher the slope of the wooden plank, the faster the car will go therefore the increase of the severity of the crash. Variables: Independent Variable – The height of the ramp Dependent Variable – Distance that the dummy flies – the velocity of the car Constant…

Life finally became so overwhelming for Newton that he began acting out and even made threats of burning down his house. However, eventually Newton was able to find solace by indulging himself in books which then led to his developed interest for mechanics and technology. As time went on, Newton enrolled in a college located in Cambridge, where he met a professor that became a father figure to him. This father figure, Isaac Barrow, encouraged Newton to achieve his best in life. Barrow set…

The first atomic model was introduced by an English chemist, physicist, and meteorologist named John Dalton. John Dalton had reintroduced the idea of the atom that had once been a theory of a Greek scientist named Democritus. However, unlike Democritus, Dalton was able to prove the existence of atoms. Through many experiments, Dalton came up with a list of properties, that he thought, all atoms shared. Each element is composed of atoms Atoms are tiny, featureless spheres All atoms of same…

Move the ramp to an angle of zero (horizontal) and draw a free body diagram of the cabinet here: On a horizontal plane, the normal force is _Perpendicular_______ to the weight. The cabinet has a mass of 100kg. It therefore has a normal force of __-100______ N and a friction force (on the horizontal plane) of _2.22N_ μ = 0.30  the ramp and draw a free body diagram of the cabinet in the box here: The force down the plane and normal force are components of __force diagrams__________. Before…

Biomechanics refers to the “study of the action of external and internal forces on the living body, especially on the skeletal system” (Dictionary.com, 2015). By using biomechanics we can examine and find ways to successfully enhance performance, develop exercise programs and modify sporting techniques (Swedan, 2013). This paper will be analyzing and evaluating the athletic event of high jump. Biomechanics will be applied to critically examine the techniques used in high jump and improve upon…

Unbalance is the most influential reasons of vibration on a rigid rotor. When designing high speed rotors and precise rotors, it is a important factor to be considered in the design. The way which used in the experiment is add the unbalance mass on the rotor, then, make whole system be balanced. The report has contained two tables which show the results collected from the experiment. It has included four diagrams, two tables and discussion section for results. Theory[1] Rigid Rotor:…
