D2 – Forced‚ Damped Vibrations with Rotating Out-of Balance Excitation (Norwood Apparatus) Introduction This lab report was aimed at investigating out-of-balance rotating masses in single degree of freedom systems‚ paying specific attention to obtaining plots of amplitude against angular velocity. This was done using a specific setup of apparatus (Detailed below) and our findings were plotted in the form of graphs and also‚ we investigated the experiment in a way which allowed

1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

Question: To measure the density of water using graphical method. Introduction: Water is the most abundant compound on the Earth and it covers about 70% of the Earth’s surface. Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. What is its density? I chose this experiment because I was really curious about the density of water‚ is it constant all the time? I doubt that because what I got from internet‚ PubChem

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which
