Maximum Safe Velocity On The Car - 1139 Words

Maximum Safe Velocity Scenario 1 The two forces acting on the car when it turns a circular path are centripetal force, FCP , and friction, Ff . As mentioned in Relevant Physics Topics, the direction of friction opposes the direction of motion, which, in this scenario, is centripetal force, and because centripetal force directs towards the center of the circle, friction directs outside of the circle (Madden et al., 2001). To calculate the safe cornering speed on a level road, centripetal force has to equal friction so that the vehicle isn’t sliding in or out of the road. The formula was developed in Calculation 4 from the Appendix. The derived formula was v=√(ÃŽ ¼s*r*g) By substituting the numerical values in the equation, the maximum safe cornering speeds were calculated in following table: *Note: ÃŽ ¼s=0.9 is dry condition, ÃŽ ¼s=0.7 is wet condition Scenario 2 In this scenario, a vehicle is turning right downwards an incline. In this case, the x component, of the normal force is greater than centripetal force and the vehicle is wanting to slide down the incline, towards the center of the curve. However, friction opposes the motion and pull the car up the incline to keep the car from sliding (Stanbrough, 2006). This is shown in Diagram 3. Before calculating the maximum speed of safe cornering, the angle ÃŽ ¸ needs to be found. This was done in Calculation 2 from the Appendix. Using ÃŽ ¸, x and y components were found and substituted to solve v in Calculation 5.

One of the systems that relates to engineering design simulations was a roller coaster. The key terms needed to know for roller coaster physics are: Kinetic energy- the energy of a body with respect to the motion Velocity- the speed of something in a given direction Height- the measurement from base to top or head of to the point to foot. Mechanical energy- the sum of potential energy. The motion and position of an object Potential energy- result of gravity pullingRead MoreReview Of Six Flags And The River Rider 899 Words   |  4 Pagesis an interesting place to go if you are looking to have fun or to learn about physics.

Inside of the whole idea of those kind of car there are a lot of information and developing that have been happen. According to Google, the main idea was and still is make everything safer, and their focus is develop a product 100% safe. When they say safe, they are not talking just about the passenger on the car but for all population.

As distinction UAVs path planning problem needs to take into account different considerations. †¢ Stealth, route must be created to avoid radar detection. To do this, velocity of UAV and altitude of UAV might be considered. †¢ Range, turning angle, maximum and minimum speed of UAV might be considered. †¢ Multiple UAVs might be used to accomplish task. These create a requirement to cooperation between UAVs. There are three different group of path planning algorithmsRead MorePrinciples of Anti-lock Braking System1199 Words   |  5 Pagesof brakes creates a force that impedes a vehicles motion by applying a force in the opposite direction. During severe braking scenarios, a point is obtained in which the tangential velocity of the tire surface and the velocity on road surface are not the same such that an optimal slip which corresponds to the maximum friction is obtained. The ABS controller must deal with the brake dynamics and the wheel dynamics as a whole plant. A locked-up wheel provides low road handling force and minimal steeringRead MoreEssay about Kinematics1733 Words   |  7 Pagesobject is moving (velocity), and the change in velocity (acceleration). This is graphed against time individually to determine if the motion is uniform or nonuniform and if the acceleration is uniform or nonuniform. Uniform motion is when an object has a constant speed and direction. Nonuniform motion is when there is either a change in speed or a change in direction. When the graphing has completed, other properties can be discovered like the instantaneous velocity. Instantaneous velocity is used to presentRead MoreBridge Analysis Essay808 Words   |  4 Pagesprojects on state highways in rolling terrain require 4% maximum grades (5% if the length of the tangent is less than 500 ft).

Also, braking distance is dependent on the condition of the road, condition of the tyres, pressure applied to the brakes and any supporting technology.

The number of entering vehicles should be equal to the exiting vehicles. But the conservation law is more complicated than the description above.
