structure is derived. Firstly it is important to determine the percentage composition of elements to work out the empirical formula. The empirical formula was found to be C10H12O and the mass of the unknown was 148.09 m/z which when calculating the molecular weight of the empirical formula it did equal 148.09 g mol -1. This means that the empirical formula is also the molecular formula. As 12.01x10 carbons +1.008x12 hydrogens + 16= 148.09 09 g mol -1. From this knowledge the unknown molecule must include

7:00 am sharp. “Perfect!” As always‚ I leap out of my bed at the first ring‚ hastily change out of my night clothes‚ and run down the stairs to eat my breakfast. Breakfast was always the same: 2 eggs; sunny side up‚ 3 slices of bacon; over-cooked to the perfect amount of crisp‚ and a glass of 2% fat milk in my favorite mug; the “Employee of the Month” mug from 3 years ago. Finally after devouring my food‚ I rush out the door to go to work‚ taking a quick detour to visit the Starbucks for my usual

I was never that close with her‚ I didn’t visit every week. The reason I had my coming of age moment was not only because she died‚ but because of my mom. “Did you have a good day at school?” my mom asked joyfully. “Yes‚ but it was school‚” I responded sarcastically.

Problem Description: The main purpose of this report is to show how to solve a 3-D finite element model of a cantilever I-shape beam‚ which is subjected to two concentrated loads (P = 1600 lb.) at the flanges of the free end along z axis. In this assignment‚ a convergence study will be used to determine the convergence of the solution with respect to mesh refinement. In addition‚ it will be used to achieve an accurate solution for problems that have sufficiently dense mesh‚ which cannot be solve
