Laboratory Report : Experiment One Title: Determination of the acceleration due to gravity with a simple pendulum Introduction and Theory: A simple pendulum performs simple harmonic motion‚ i.e. its periodic motion is defined by an acceleration that is proportional to its displacement and directed towards the centre of motion. It can be shown that the period T of the swinging pendulum is proportional to the square root of the length l of the pendulum: T2= (4π2l)/g with T the period in

The Introduction Abstract Through examining the simple harmonic motion of a mass hanging on a spring‚ three investigations were conducted in the experiment. The experiments include the relation between the period in oscillations and mass‚ and figuring out if the period vs. mass graph should go through the origin and lastly‚ finding the mass needed to create a one second timer. It was investigated by placing a motion detector under a spring that was attached to a clamp which was attached to a retort

Abstract— In the conventional buck converter the supply current is discontinuous which may produce electromagnetic interference (EMI). In order to minimize the EMI problems an interleaved buck converter with continuous supply current has been introduced. Also due to the advantage of improved step-down conversion ratio‚ the interleaved buck converter can be used for high step-down and high frequency applications. The main features of the converter also include lower switch stress and lower output

It was a great day to break my arm. The accident happened right after I made the best choice of my life to jump off a tree into the water. Instead of caring about what could happen to myself‚ I thought it was the best decision. When I was about 8 years old‚ my family and I went up north to our cabin up in Antigo‚ Wisconsin. It was a nice sunny day‚ and that morning I remember waking up and going out for breakfast. When we came back from breakfast‚ we took our speed boat out onto the lake and went

What does tradition mean to you? In the Sound of Waves tradition is valued greatly. The Sound of Waves by Yukio Mishima deals with two young adults who fall in love with each other and have to deal with the gossip of the town. Mishima uses characterization to develop the theme “Tradition will always be valued more than modernization” throughout the Sound of Waves. Mishima uses the relationships of the townspeople to represent the importance of tradition on the island. “Like this I should be able

| 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
