What is Overclocking? Overclocking is the process of making various components of your computer run at faster speeds than they do when you first buy them. For instance‚ if you buy a Pentium 4 3.2GHz processor‚ and you want it to run faster‚ you could overclock the processor to make it run at 3.6GHz. ¡Disclaimer! WARNING: Overclocking can F up your stuff. Overclocking wares down the hardware and the life-expectancy of the entire computer will be lowered if you overclock. If you attempt to overclock

Acceleration Worksheet 3 Worked Example A cheetah running at 20 m s−1 slows down as it approaches a stream. Within 3.0s‚ its speed has reduced to 2 m s−1. Calculate the average acceleration of the cheetah. Solve the following: 1. A sports car‚ accelerating from rest‚ was timed over 400 m and was found to reach a speed of 120 km h−1 in 18.0 s. a. What was the average speed of the car in m s−1? b. Calculate the average acceleration of the car in km h−1 s−1. c. What was its average

calculates its location‚ movement and relative speed‚ using the reflected radar waves. The system is able to recognize whether a particular vehicle is occupying the lane ahead. As soon as the car ahead changes lanes again‚ your vehicle picks up speed again‚ accelerating to the same constant speed as before. ACC adjusts your car ’s speed to the changing flow of the surrounding traffic.If a vehicle is detected in the lane ahead‚ the ACC system adjusts the speed of the vehicle by slowing the engine or by

movement. It can be used to change the direction‚ speed‚ force‚ or type of movement. The output of a robot or any machine is motion and force in some form. A drill press‚ for example‚ has two kinds of motion: rotary and linear. The drill spinning provides the rotary motion; moving the drill down through the material is the linear motion. The force or torque applied to the drill must be sufficient to turn the drill through the material. Also‚ the speed of the drill bit must be within a given range. If

1 Velocity‚ Speed‚ Acceleration‚ and Deceleration The goal for today is to better understand what we mean by terms such as velocity‚ speed‚ acceleration‚ and deceleration. Let’s start with an example‚ namely the motion of a ball thrown upward and then acted upon by gravity. A major source of confusion in problems of this sort has to do with blurring the distinction between speed and velocity. The speed s is‚ by definition‚ the magnitude of the velocity vector: s := |v|. Note the contrast: –

number of revolutions per minute‚ it is advisable for the operator to increase the gear‚ to drop the revolutions on the motor‚ yet still keep the same amount of power created. This reduces wear on the engine‚ allows more control‚ and allows greater speeds. Although‚ in practise‚ the main use of a Gearbox is to act as a reduction gear. These can be variable or non-variable‚ depending on the application. In other words‚ if when the motor is turning 2500 rpm the output shaft is turning 500

It is produced when something vibrates causing its the medium (water‚ air‚ etc.) around it to vibrate as well. In common everyday speech‚ speed of sound refers to the speed of sound waves in air. Sound travels faster in liquids and non-porous solids than it does in air. In this experiment‚ velocity of sound in solid‚ liquid and gas were determined.
