forced damped transverse vibration of a beam and verify Dunkerley’s empirical formula. According to Dunkerley’s empirical formula‚ 1f2=1fb2+1fω2 where f referring to the natural frequency of heavy beam with central load fb referring to the natural frequency of heavy beam only fω referring to the natural frequency of light beam with central load M By using the results of light damping‚ Dunkerley’s empirical formula would be studied and verified by comparing the calculated resonant frequency

Heron’s Formula History of Mathematics University of Phoenix October 22‚ 2012 The event that I chose to discuss is Heron’s method that was written about in the three book series called metrica discovered in the period of about 60 AD. His formula for calculating the area of a triangle was one of the formulas which was written about in the books. Heron of Alexandria was also very well known by Hero. Their has been much debate on the birth

The Hubbart Formula Where would a hotel manager start in determining the fair price for a guest room? What is a fair value? This question has daunted innkeepers from the beginning. Charge rates too high‚ and no one will stay with you. Setting rates too low‚ and the owner makes less money. For many years in the beginning of the modern hotel era‚ hotel managers simply guessed. As unscientific as this approach sounds‚ it did work to an extent. After a hotel has been in business

prevent buckling if the temperature range is -30Cº to +50Cº? I know I use the formula: L = LoT L = ? (Change in length of the slabs. We are solving for this.) = 12e-6 (Coefficient of expansion. I looked it up on page 388.) Lo = 14 m (Initial length of slabs.) T = 30 Cº (50Cº - 20Cº) (Change in temperaure. You only care about the hottest number since you are dealing with expansion.) I then had the formula: L = e14 m 30Cº L = .00504 m L = .50 cm The space between

Title: Formula of a Hydrate. Objective: Determining the percentage of water and the chemical formula of a hydrate. Background: Water has a polar structure and it has positively and negatively charged parts within each molecule. This gives it a strong attraction toward ions. The ions in some salts attract and form strong bonds with water molecules. These salts‚ when they have absorbed water‚ are called hydrates. Anhydrous salts are salts that can form hydrates but which have had all the water

Return on Shareholders Funds (ROSF) Ratio Definition: The Return On Shareholders Funds (ROSF) ratio is a measure of the profit for the period which is available to the ordinary shareholders with the ordinary shareholders’ stake in a business. Formula: Return On Shareholders Funds = ((Net profit after taxation & preference dividend) / (Ordinary share capital + Reserves)) * 100% Example 1: If the net income of PPC Ltd is $80‚000 whereas shareholder’s funds are $500‚000. Then‚ the ROSF =

the real world Every day‚ everywhere people are using technology to check email‚ calculate tax‚ and talk with each other. Technology has greatly affected the social structure today and in Fahrenheit 451. Technology has effected how the TV controls our lives‚ how we communicate with one another‚ and how strong the social structure is In both the real world and Fahrenheit 451. Similarly to the real world‚ in Fahrenheit 451 the TV is a habitual action that diminishes social contact. In the real world
