CLASSIFICATION OF VIBRATION Vibration can be classified in several ways. Some of the important classifications are as follows. •Free Vibration. If a system, after an initial disturbance, is left to vibrate on its own, the ensuing vibration is known as free vibration. No external force acts on the system. The oscillation of a simple pendulum […]

BALANCING OF ROTATING MACHINES The first thing to be explored to control vibrations is to try to alter the source so that it produces less vibration. This method may not always be feasible. Some examples of the sources of vibration that cannot be altered are earthquake excitation, atmospheric turbulence, road roughness, and engine combustion instability. […]

Cyrus Newton Ray was a man who found his sole purpose of fulfillment by finding evidences of artifacts from the past. His original studies were focused on the medical field: osteopathy, which he received a degree for in June 2, 1909. It is bizarre to know that archaeology was not Cyrus N. Ray’s field of […]

The article Effects of nursing rounds on patients’ call light use, satisfaction and safety as reported by Meade, Bursell, & Ketelsen (2006) examines the possible implications that implementation of regular rounds by nurses might have on patients and nurses. The purpose of the study is to determine the extent to which the frequency of responding […]

Aero-space engineering is a new field of engineering that has tight links with the fields of astro-physics, theoretical physics, chemistry, structural engineering, and space dynamics. It is definitely an old form of engineering if we refer to the space launch in the 1960’s, but this field is considered new because the new theoretical propositions in […]

Objective: * To determine the how changing the throwing arm length and/or the counterweight mass affects the distance and direction that a can is thrown by a trebuchet. Trebuchet Test Results Our trebuchet had some technical and engineering damage and it did not worked properly. When we launched the sauce can, it moved in opposite […]

Thermodynamics of the Dissolution of Borax Lina Jawadi Objectives: Study a system of salt and water solution. Determining a variety of important thermodynamics quantities from the solubility information at various temperatures. Background: The salt and water solution in this experiment has a relatively simple solubility equilibrium of borax in water. Na2B4O7 . 10 H2O 2Na […]
