the time period between 1900 and 1930 saw many technological innovations‚ from the air conditioner to the disposable razor blade. From the tank to the cruise missile. Many of these inventions made our lives easier while others made them more deadly. the first of these inventions is the air conditioner. While many inventers beforehand had made crude means of cooling the air‚ but all proved to be ineffective. the earliest method of cooling the air was putting bowls of ice in front of a fan and the

programs should not be cut during the nations’ budget crisis‚ but rather supported and funded even further. The act of participating in music has almost completely dissolved. Although some people listen to music while sitting behind the steering wheel of their vehicle‚ they are hardly interacting with music as it was originally intended. Martin Luther wrote some of the first Protestant hymn books so congregations would not simply plop into a pew and listen to monks sing ancient spiritual chants

IMPACT OF A JET OBJECTIVES: To measure the force generated by impact of the jet on vanes of various shapes. To compare the results from the experiment with the theoretical calculations. APPARATUS: The Jet Impact Apparatus Volumetric Hydraulic Bench/Water 3 different shapes of vanes; Flat Plate‚ Conical Cup‚ and Hemispherical Cup Stop Watch 1. INTRODUCTION One way of producing mechanical work from fluid under pressure is to use the pressure to accelerate the fluid to a high velocity

1.0 ABSTRACT The purpose of the impact of jet experiment is to design a system to determine the force generated by the impact of jet on a variety of target vanes. A formula is given to calculate the reaction force at the different vanes caused by the jet. At the end of the experiment‚ the data collected and results calculated will then be compared to theoretical values which are given. Students are expected to be able to come to a conclusion regarding the relationship between the reaction force

Although the exact date of when rockets were first invented is still unclear‚ it is believed that the Chinese invented the first “rocket” (“The History of Rocket Science”). Moreover‚ the Chinese used gunpowder‚ invented in around 100 A.D‚ and positioned it in Bamboo sticks for religious festival tradition (“The History of Rocket Science”). Large bamboo sticks were created and decorated by Monks and villagers‚ then blasted skyward to inform the Rain God Phaya Thaen that it is time to send rain down

Teddy Roosevelt was a fine president‚ indeed. Along with leading our country‚ he also put in the makes of the Panama Canal. This idea sparked Teddy‚ and couldn’t have been more successful. A canal is like a waterway filled with underwater stairs. The Panama Canal was nothing but hard work‚ and dedication. Many workers went through hard labor to complete the job‚ but it turned out to be an outstanding landmark in U.S history. While Teddy was president‚ he wanted to prove his dominance throughout

Impact of technology Heading TECHNOLOGY" - this word is derived from Greek word "—techno meaning an art‚ skill or craft and –loggia meaning the study of something or branch of knowledge of a discipline. With the advancement in technology‚ human life is more comfortable like never before. There is almost no place that you can go where technology hasn’t been used. Technology affects our daily lives in everything that we do; it saves time (time is money-more so these days)‚ creates a world of endless

1.0 ABSTRACT The objective for this experiment is to verify the momentum equation experimentally through the impact of jet against deflectors. There are four deflectors used in this experiment. The four deflectors are plate‚ hemisphere‚ slope and cone. The loading weights to be used are 0.8 N‚ 1.0 N‚ 1.5 N and 2.0 N. In this experiment‚ the time taken for the water level in the volumetric tank to raise from 10 to 20 L is determined by using a stop watch. The flow rate‚ calculated force and the error

marvels have changed how we live‚ work‚ sleep and prioritise. All these have acted in concert to create opportunities and issues unimaginable decades ago. I chose this question because not many people recognise the boons and sometimes the banes these inventions have brought forth. I also believe that it is high time we pay tribute to the engineers‚ scientists and inventors whose ideas and technologies have bettered our material existence. The launch of Sputnik 1 in 1957 heralded the dawn of a new age
