Force

Bending Strength requirement This is the first body requirement and its task is to support all the vehicle subsystems. The body in static is going to suffer bending due to the weight of the components, passengers, fuel and cargo, Figure 42. Similar to a beam simple supported, the very first requirement is that the structure bend sufficient to absorb the energy due to the weight, but has to withstand the weight under different loading scenarios. Figure 42: Body loading under a static scenario…

When imparting a large force to the environment, a human will utilize his entire body to develop a mechanical advantage. For pushing, pulling or wielding a heavy object or tool, a Master of Science Thesis Jijju Thomas 2 Introduction stable stance is found with all the points of contact considered. When producing a pushing force, a human’s stance often consists of either one foot or both feet displaced some distance from the object being pushed. The two stances are called the ‘feet-apart’ pose…

loop-the-loop is a type of large scale centrifuge, as one approaches the loop, the rider's inertial velocity is straight ahead. However the track of the roller coaster keeps the car and therefore the rider, from travelling in a straight path. The force of a rider's acceleration pushes them from the coaster-car floor, and their inertia pushes them into the car floor. As one travels upside down on the loop, he or she's own outward inertia creates a false sense of gravity that…

Isaac Newton’s Laws of Motion and Crumple Zones Crumple Zones design and function The crumple zone is the front and the rear of a motor vehicle that is designed to crumple without difficulty and to absorb the force of the impact in a crash. Crumple zones are also known as crush zones and they absorb energy in a crash so that it doesn’t transmit to the occupants as much. The zones are now made in cars to prevent death for occupants or serious injuries when in a crash. The front of the vehicle…

The key objective of this laboratory experiment is to help the students understand the concept of shear stress and normal stress on a cross sectional area of a surface or rocks, and to be capable of constructing failure envelops. As we spread or stacked the pennies on a piece of paper placed on the table, we inflict a normal stress on the paper. We then created the shear stress by putting pennies into the cup that was connected to the paper on the table by a strain, and the number of pennies…

As these two forces are equal and opposite, the resultant force is equal to zero, and by Newton’s first law, the handle remains at constant motion resulting in no feeling of ‘shock’ in the hand. The next point of interest is the vibration node. Using terms from wave theory, the node is…

understand deeper all the company and used some wrong communication style to made her fail. First, she only use three or four months to find a plan and send email about her plan to field sales force. Because she is a fresh man in Kauflauf, she lacked formal authority over either the development engineers or the sales force, she cannot persuade them by her analysis and explanations. For her plan, she did not solve some problems which is consultants are too busy to follow up her proposal. So she…

to understand drag, as it affects the distance an object is able to travel if it is not influenced by outside forces, such as a cannons projectile. The equation for drag is shown below. F=pCA/2 v^2 p = The density of the air. C = The drag coefficient of the projectile. A = The area of the object that the air presses on. v = The velocity of the projectile. The drag equation returns a force as newtons of energy. For example, p = 1.225 kg/m3 (the density of air) C = 0.5 (the drag of a sphere) A =…

10/03/2017 Purpose The goal of this experiment was to learn how to apply computerized instruments in physics. In addition, this experiment aimed at enhancing practice on how to use three equipment in the lab: the rotary motion sensor, high resolution force sensor, and motion sensor. Further, this experiment sought to clarify the circumstances under which the instruments fail to comply with expectations. Results/Data Part 1: The Motion Sensor Motion Sensor’s Measurement of Distance on…

ground, it keeps moving because of inertia and accelerates 9.8m/s/s due to gravity pulling it towards the ground and the opposite happens when the slope of the hill is positive. If the track are tilted upwards the gravity still applies a downward force hence the cars…
