of the lightbulb was arguably one of the most important in recent human history. It also was however‚ perhaps one of the most detrimental things to modern society. As we all depend on light to function now at all hours of the day. For all of the problems that the lightbulb solved‚ it gave rise to just as many. Although some may argue that humanity is better off with this invention‚ there are a select few who refute this claim and stick to saying that humanity’s invention of the lightbulb was only

materials and using Solid Edge to determine the Second Moment of Area for the different cross-sections. [pic] Equations Use units: Force (N)‚ Length (mm)‚ Stress (MPa) E = Young’s Modulus or Mod of Elasticity (MPa) I = 2nd Moment of Area or Area Moment (mm4). Can calculate using SolidEdge sketch. BENDING [pic] In our case‚ we must first convert the mass to Newtons (N). W = kg * 9.81 L is the span length in (mm). I is the Second Moment of Area in (mm4). We can calculate this for a rectangle

“… Though Thomas Alva Edison is almost always credited with having invented the lightbulb‚ an earlier version was developed in England by Sir Joseph Wilson Swan. However‚ Edison was an important pioneer who went on to make the first successful electrical system.”(Collier 66). In 1878 Joseph Swan made a workable version of an electric light bulb‚ using a carbon filament. (Collier 66) An incandescent bulb consists of a filament‚ which today is made of a wire of tungsten‚ and Anchor wires‚ which hold

Thomas Edison’s invention of the lightbulb was so significant that it is still effecting society to today. Thomas Edison’s lightbulb had to consist of three things‚ the first being a durable incandescent material‚ the second thing the lightbulb needed was to eliminate the oxygenation from the bulb‚ and the last thing the lightbulb needed was a filament material of high resistance. The first lightbulb was going to be made out of platinum‚ however‚ platinum was very expensive to distribute to homes

PEARSON PRODUCT MOMENT CORRELATION COEFFICIENT Definition It is the measure of the linear correlation between two variables X and Y It is the measure of the strength of a linear association between two variables and is denoted by r. It tells you how strong the linear correlation is for paired numeric data e.g. height and weight. The Pearson correlation coefficient‚ r‚ indicates how far away all these data points are to this line of best fit. Development It was the imagination and idea of Sir Francis

The Lightbulb war were a period of great strangeness and confusion in the world of Watt. Between the two largest nations on Watt‚ the Halogen Empire and the Fluorescent Republic. The average cost per soldier was 84 Watt Dollars per month. The war got to the point that just about 47 states had become a battleground. The expansion of outposts during the war was extensive as 19 million schools‚ Homes‚ Businesses churches and farms were transformed. The Fluorescent Republic’s military budget alone was
