| SPEED DETECTION USING DOPPLER EFFECT AND RADAR | | | INTRODUCTION Although there is good road safety performance the number of people killed and injured on our roads remain unacceptably high. So the roads safety strategy was published or introduced to support the new casualty reduction targets. The road safety strategy includes all forms of invention based on the engineering‚ education and enforcement and recognizes that there are many different factors that lead to traffic

WIRELESS VIBRATION MEASUREMENT SYSTEM Vibrations are caused due to mechanical oscillation of a structure about an equilibrium point. There will be vibrations involved everywhere where there is any rotating system‚ mechanical system is involved. The vibrations involved at in these places will of high frequency. There will some places where the vibrations of lo0w frequency will be present which will also disturb the normal operation of the system or faultiness in the values measured by the system

CLASSIFICATION OF VIBRATION Vibration can be classified in several ways. Some of the important classifications are as follows. • Free Vibration. If a system‚ after an initial disturbance‚ is left to vibrate on its own‚ the ensuing vibration is known as free vibration. No external force acts on the system. The oscillation of a simple pendulum is an example of free vibration. • Forced Vibration. If a system is subjected to an external force (often‚ a repeating type of force)‚ the resulting vibration

First of all‚ tide is the rise and fall of water caused by gravitational forces of the moon and sun on the oceans of the earth. Generally speaking‚ tidal cycles contain two high tides and two low tides each day. During the time between high and low tides there will obviously be current flow. The time between high and low tides is a little over 6 hours and the entire tidal cycle repeats itself approximately fifty minutes later each day. So if you know that low tide is at 0800 today you can estimate

Objectives Measure the detector frequency for waves emitted from a slowly moving source as that source is approaching the detector. (Exploration 1) Calculate the detector frequency for waves emitted from a slowly moving source as that source is moving away from the detector. (Exploration 2) Sketch the wave-front patterns for wave sources with various source speeds. (Exploration 3) 2 Description of Activity In this activity‚ you will study waves that travel from a moving source to a detector

compared to the official class syllabus. The students were able to accomplished the job by equally dividing the time into two. The first experiment was about Kundt’s tube. In this experiment‚ longitudinal sound waves will be produced in a metal rod and an air column. Using the properties of wave motion ‚ the frequency of the sound and the speed of sound in the rod can be determined. For this experiment setup‚ following materials are needed such as a Kundt’s tube apparatus‚ a meter stick‚ a piece of

Roenyl Tisoy Mr. Boyd AP Literature 27 August 2012 Title In The Sound of Waves‚ Yukio Mishima explores the contrast between the corrupt influences of western civilization versus the power of nature. Mishima idealizes Japan through descriptive language and also through the characters. Mishima presents Yasuo as the antagonist to invoke the reader’s appreciation for nature and ultimately‚ Japan. He uses characterization to associate Yasuo‚ the antagonist‚ with corrupt Western influence. Furthermore
