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 first day of kindergarden. It was a sunny day in January 2001‚ I was all alone with no one to talk to. Scared and nervous‚ but she walked over and started talking to me. I knew we would be best friend. We were closer than ever and we spent every moment together. Ever since then‚ it had been nothing but a strong friendship. On a clear summer night‚ I was staring up at the sparkling sky‚ swaying on the playground swing. My best friend of 12 years sat quietly on the swing next to me. Suddenly‚ there

Obviously‚ this triggered my own interest in what this author‚ that I originally found so predictable‚ had to say. From the moment he set foot on the stage to when he said goodbye‚ I was intrigued. Diaz evoked a casual atmosphere; through cursing and joking he made the crowd feel comfortable. What I found most interesting was how he explained the different views between him
