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

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.

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

Crane’s thoughts for the use of the Western formula are just approaches towards the west‚ from the
