The aftermath required that drivers wear neck and head restraints. Helmets were further improved and safety precautionary became key concerns. NASCAR also joined forces with Indy Car and the team from the University of Nebraska-Lincoln. The results of their merging introduced the Steel and Foam Energy Reducing systems known as the SAFER barrier. The barrier is basically a stack of eight inch by eight inch steel tubes, cabled and bolted to a solid wall with foam pillars cushioned between them. In…

both internal and external forces. Internal forces occur within the bridge, through tension, compression, bending, etc. External forces are applied to the outside of the bridge, and can be static or dynamic. The static load of the bridge is the bridge itself, and the weight of its members and components. This is created by the force of gravity pulling on the members of the bridge. The dynamic load moves and changes, such as traffic, people, wind. It is created by the force of gravity on an…

variables involved like air pressure, rotation of the ball, and aerodynamics. These are very important factors when a baseball is thrown. A Big part of velocity is the air pressure, this is because of a separate topic called the Magnus Effect - a force exerted on a rapidly spinning cylinder or sphere moving through air in a direction at an angle to the axis of spin. This is what I am testing in this experiment using the average velocity formula v=(Df-Di)/t. I will test the change between the…

An Experiment on a Bird in the Air Pump is a painting by Joseph Wright of Derby (An Experiment on a Bird in the Air Pump). Painted in 1768, oil paint on canvas, it serves to express the Industrial Revolution (An Experiment on a Bird in the Air Pump). The painting’s dimensions are 183 centimeters tall and 244 centimeters wide (An Experiment on a Bird in the Air Pump). This paper’s purpose will be to analyze and interpret not only Wright’s art, but his life and era as well in an effort to…

The Poi Pounder Poi pounders are a powerful tool used in my Hawaiian culture . Poi pounders start off as an ordinary rock, like how I was born at birth. An ordinary child , The pedestal which is the bottom of the pounder , represents what holds me and my knowledge. The core represents how my family shaped me into the person I am today , and the top represents my religion. Starting from the bottom of the poi pounder , the pedestal represents my knowledge and what holds me . In my culture we…

air resistance and snow resistance. A skier minimizes his air resistance (drag) by reducing his projected frontal area. He does this by going into a crouch position, which (along with improving his ability to hold balance) results in a lower drag force. This results in a direction opposite his velocity, slowing him…

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…

Stress is a state of well-being when an individual feels strain due to demanding or adverse circumstances. Stress can factor in our lives in a various amount of ways in the form of daily hassles, major life events, conflict, and frustration. Those are not the only things that affect a person's well-being, having a mental health issue can also be negatively emotionally and physically taxing on an individual's physical and mental well-being. About 44% of Americans feel more stressed than they did…

track? Well I sure have, this is all due to centripetal force. This is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. The curves of these loops on rollercoasters resemble the curves of a circle. The coaster is continuously changing its direction while moving through the loop. This change in direction is caused by the presence of unbalanced forces and results in an acceleration. The acceleration of the…
