Although different in many respects‚ liquids and gases have a common characteristic in which they differ from solids; they are fluids‚ lacking the ability of solids to offer permanent resistance to a deforming force. Fluids flow under the

History of IKEA IKEA‚ the world’s largest furniture manufacturer‚ began from humble roots near Agunnayrd‚ Sweden. In the late 20’s and early 30’s a young Ingvar Kamprad began buying matchsticks in bulk‚ only to sell them individually to neighbors for a small margin. The business savvy boy expanded his sales to include Christmas cards‚ seeds‚ pens and pencils. But it wasn’t until‚ at the age of 17 with money he received from his father for his academic performance‚ did Ingvar have the means

Making sure that your initial velocity of the ball is 0 m/s‚ drop the ball and measure (using the stopwatch) the time that it takes to hit the ground. Repeat at least 5 times (discard any really bad measurements) Calculate average time Use the kinematic equation - d vit at2 to calculate the acceleration due to gravity.

Tennis is a highly competitive sport with participation in over 200 countries throughout the world. It is a non-contact racquet sport which requires aspects such as strength‚ power‚ speed‚ coordination and agility. Like any sport‚ tennis places specific demands on the body which can predispose any player to injury. These demands placed on the body result in injuries specific to the game. It is said by Pluim et al (2006) that although many injuries that occur in tennis are common in other sports‚

CHAPTER-1 INTRODUCTION 1.1GEARBOXES: Usually‚ found near motors of some sort‚ gearboxes are used to reduce the load on the motor by using the motor ’s own momentum to keep it turning. Once a motor has reached a 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

of heatand mechanical power for the design‚ production‚ and operation of machines and tools.[1] It is one of the oldest and broadest engineering disciplines. The engineering field requires an understanding of core concepts including mechanics‚ kinematics‚ thermodynamics‚ materials science‚ structural analysis‚ and electricity. Mechanical engineers use these core principles along with tools like computer-aided engineering‚ and product lifecycle management to design and analyze manufacturing plants

Transfer. The purpose of this manual is to serve as instructional book for students‚ technical staff and instructors to assist in performing and understanding the experiments in Transport Phenomena. In the second edition‚ two new experiments on kinematic viscosity and vapor pressure determinations have been included in Fluid Mechanics and Mass Transfer sections respectively. The old experiments have been revised to eliminate errors and induce clarity. This manual will be available in electronic form
