Front lighting System to control these four LED lights. The lights will turn together when the car is cornering. Between these two headlights there is a big spoiler. The spoiler is creating down force to keep the car on the ground. The vents behind the front fenders are not only creating more down force but also cooling the brakes. There is a big grille between two headlight can get more air to cool down the engine. The cooling system is very important for a powerful car. The new GTR has a 3.8-liter

static friction. Keywords: static friction, coefficient of static friction, critical angle 1. Introduction Friction is the force that opposes motion. It is the resistance of surfaces moving against one another. It is a force that plays a very important role in our lives. Without it, we cannot walk, do our daily chores, and even slide endlessly due to external forces. This phenomenon remained unknown to the early people until Leonardo Da Vinci (1452-1519) studied and analyzed its importance in

the clinic be innovative in its personnel policies, allowing full time employees a three-day weekend, reducing the number of computed to and from work each week. Evaluate the work of the task force from a managerial perspective. From the results presented by the task force, the research has shown that alternative schedules didn't necessarily reduce work-family conflict, although having a decrease in employee absenteeism. There are many generalizations that can

secured into place. 8. Sample was brought to cell pressure of 3 kPa. 9. Sample was conditioned for shakedown 10. Cyclic loading was applied to sample, with a loading duration of 0.1 second and a rest period of 0.9 seconds, displacements and forces during this loading were recorded using supplied software. 11. This loading was applied in groups of five with a 95 second rest period between sets of load application. A total of three sets of load applications were applied to the sample.

determine the acceleration of the weights of an Atwood’s Machine, both experimentally and theoretically. We will attempt to verify Newton’s Second law which is a mathematical statement relating force, mass, and acceleration. Newton’s Second law states that acceleration, a, is directly related to net force, F, and inversely related to mass, m. Naturally this give F=ma. Using the Atwood’s Machine experimental acceleration data (for 10 different runs with 10 different combinations of masses) will be

has links to Greek philosopher Aristotle's concept of potentiality. Potential energy is associated with a set of forces that act on a body in a way that depends only on the body's position in space. This allows the set of forces to be considered as having a specified vector at every point in space forming what is known as a vector field of forces, or a force field. If the work of forces of this type acting on a body that moves from a start to an end position is defined only by these two positions

Where have the women gone? They are only seen when the sun rises or late at night, and sometimes; never. It is 7 AM in the morning; women have slowly begun streaming down the streets in order to be at their workplace by 8 AM. This is due to the 1 hour walk they are required to do every day solely because of not being able to pay for a bicycle rickshaw. Each year there are over 9 million garments sold to the USA which are mostly produced by women of the age of 16-25 who have been forced to work
