Hardness Testing Lab 1 Moriah Ausherman E882U679 Kunza Arifa ME-251-10959 Thursday 3:30 Experiment Date- 8/31/2017 Due Date- 9/7/2017 Introduction: The purpose of this lab is to ascertain the hardness of two different materials. One material is aluminum the other will be determined through testing. Hardness is defined as a material’s ability to resist plastic deformation by indentation. Harder objects are more likely to resist deformation. The results of a hardness test will be…

Proportional reasoning is a kind of mathematical reasoning that encompasses a logical comprehension of various evaluations and co-variations. Proportional reasoning allows an individual the ability to reason mathematically and is a demonstration of how a number of pieces of information are stockpiled mentally. We deal with diverse proportional information on a daily basis, such as reading temperatures, relational spatial contrast, and calculations of densities all of which is central to…

The T-41 (i.e., the military version of the Cessna 172) had a "simple mechanical" flight control system using direct mechanical linkages. Direct feedback of forces acting on the control surfaces to the control stick (or yoke) provided a natural feel. The feedback was by the "seat of the pants". The trim system was a mechanical linkage connected directly to a trim control wheel in the cockpit. There is no warning in the T-41 if the trim was set incorrectly. It is the pilot’s responsibility…

Set the bar to the mid thigh level on the Smith Machine. Load the bar appropriately and hold it with pronated hands. Use wrist wraps for heavy lifts. Lift the bar with straight back and extended arms. Now move to the standing position with a narrow posture. Now lower the bar with straight knees, but only bend at the waist with a stiff back. Stop only when you stretch your hamstrings. Reverse the motion to again stand straight. Snatch Deadlift It is the first part of snatch weightlifting. Select…

Did you know parachutes come in all kinds of different shapes? The shapes vary from circles to triangles. However which one is the fastest? There are many factors that effect the speed of parachutes. Kinetic and potential, for example, influence the parachutes speed and movement. When a skydiver jumps out of an airplane gravity pulls him towards the ground and he doesn’t have enough air resistance to safety land on the ground. That’s where the parachute comes in! When the skydiver pulls the…

Biomechanics is the study of the body as a machine. This study of the body looks at the internal and external forces that act on the body and the movements that these forces produce. By grasping biomechanical concepts, it enables us to programme our bodies to correct technical errors, reduce injury, move our body with precision and understand the importance of equipment design. This can be used in all sports including volleyball. I will be analysing myself and how I compare to a professional…

remain at rest or in a uniform motion, unless an external force acts on it. This is basically also the definition for inertia. In other words, the state of motion of an object will not change unless there’s an external force that acts to change this motion. Therefore, velocity is either zero, or remains constant. Newton’s second law: This describes the change in velocity of an object when acted upon by an external force. Thus, the force exerted on an object is equal to the constant mass of the…

There are six fundamental movements or primary movements which occur where the joints are located between the body segments. These movements are flexion (frontal plane, and shoulder) extension, abduction, adduction, rotation, and circumduction. As explained in our text, flexion is a decrease in the angle between two body segments, whereas extension is an increase in the angle between two body segments. Abduction is a movement away from the body, whereas adduction is a movement toward the…

How Bad Health Can Affect Your Work Every year, people make resolutions that they are going to work on living a healthy lifestyle. And yet, somehow by March, those health goals seem to get pushed to the side. There’s no need to beat yourself about it. It happens to the best of us. Sometimes, what’s needed is another form of motivation. What if you knew that bad health would ultimately affect your bottom line, i.e., your financial wellbeing? Studies show that healthy employees have increased…

kinetic energy where as the height corresponds with potential energy. Although speed and the transfer of energy are main sources of acceleration another force involved in the acceleration of the roller coaster is gravity. (Normani,…
