Brass Reports Samples For Students

Abstract

This experiment aims at determining the Young’s Modulus (E) by using the strain gauge technique. It is determined for a simply supported beam by measuring the strain in the beam when it is loaded in 3 point bending. i.e. load is applied exactly at the center of the beam. The bending of a beam is an example of Hooke’s Law, which states that, when an elastic body is strained in any way, the deformation is directly proportional to the applied stress provided the body is not strained beyond its elastic limit. In this experiment, Young’s Modulus is studied ...

Abstract

This lab study was undertaken to analyze the effects of torque forces and shear modulus of rigidity on three circular solids namely, half-hard brass (60% Cu and 40% Zn), 0.1% and 0.4% carbon steel. This was done by subjecting the samples to a shearing stress and by noting down its angular displacement. The maximum torque of each sample was calculated and compared. Their polar moment of inertia was also calculated to assist in analysis. The value of shear modulus of rigidity of each of the samples was determined using a graph which related torque and angular displacement. It was ...

Introduction

Torsion test is very important test to know the resistance of material of a material when it is subject to torsion. Resistance of torsion can be denoted by shear modulus which is derived from performing torsion test and creating a graph of angle of twist vs torsion. By measuring the slope of the graph shear modulus is evaluated. Another property of material, Young’s modulus, can also be determined from the value of shear modulus if value of Poisson’s ratio is known. In this lab experiment two metals were ...

Methods of Heat Transfer

Conduction
The first method through which heat is transferred from one object to another is conduction. Conduction occurs in liquids and solids through transfer of kinetic energy present in one particle to the immediate particle(s) in its surrounding. By considering the bonds existing between atoms and molecules in solids as elastic links, the vibration of one particle due to increase energy level caused by heat, the next in its line vibrate too. This process is replicated in adjacent particles thereby allowing transfer of thermal energy from a body with a higher temperature as compared to the one with low ...

The Wind Ensemble conducted by Greg Miller at the University of Alabama was really an eye opener in every respect. The music on offer was indeed wide ranging and full of modern sounding effects and all this combined together shows that the University of Alabama Wind Ensemble is truly a top notch orchestra.
The first work on offer was the Kirkpatrick Fanfare by Andrew Boysen which was composed in 2001. Here one could admire the voluptuousness of the sound of the Alabama Wind Ensemble which demonstrates the wide ranging varieties of this ensemble. Although some of the top brass ...

Velocity of Longitudinal Pressure waves in Solid Bars

The purpose of the experiment is to compute the Young Modulus of specific rocks and metals by determination of the velocity of longitudinal pressure waves through the samples

Introduction

The speed of any mechanical waves of most material posses a unique relationship with both the elastic property of the material and the inertial property of the medium. The velocity of a mechanical wave is directly proportional to the square root of the quotient of elastic property and the inertial property.
V= Elastic propertyInertial property
There are three basic types of pressure waves; infrasonic waves, sound waves and ultrasonic waves. Infrasonic ...

Every spring, students and professors of the Glendale College, as well as members of the local community, have a chance to enjoy annual concerts performed by the Glendale College Community Orchestra (Glendale.edu, n.d.). On May 22, the Orchestra performed in a huge concert, which took place at the Mainstage Auditorium.
Bethany Pflueger was the conductor of the Glendale College Community Orchestra, and, probably, this was the key thing why the performance was so successful. This concert featured Glendale College Concert Singers, and it was also led by Chris Rios and Chris Coulter as musical directors.
The Glendale College Community ...

Storyville or as the locals simply called “The District” was the area of ​​New Orleans, residents and visitors of which attended for the carnal pleasures they could receive from living there numerous priestesses of love. Music lovers went there to listen to jazz virtuosos.
Actually, this “red light district”, or Storyville, was established in 1897 by the authorities of New Orleans to put prostitution to order. The authorities legalized these “activities” based on the schemes tested in the Dutch and German port cities. Storyville was named after Sydney Storey, city council member, who is considered one of the founding ...

ABSTRACT

In the vibrating beam experiment, an aluminum cantilever beam was made to vibrate. An accelerometer transducer was used to convert the mechanical vibrations into a signal that was fed into an oscilloscope via a power supply. The oscilloscope mapped the signal into a sine curve and displayed it on the screen.
The oscillations’ decay curve was studied and the beam’s damping ratio was determined. The decay curve’s logarithmic decrement was used to determine the beam’s damping ratio and its natural frequency.
The beam’s damping ratio was observed to be underdamped at a damping ratio of 0.0066.

Analysis of women and minorities in the labour industry in America

Previous decades had set a clear distinction between the jobs women and the minority groups in America could participate in and those that the white American males could that had set a trend followed for many years. This disparity set the males on a higher income scale than the females and the minority and set the disparity between white collar jobs and blue collar jobs. The minority group were only allowed to do the blue collar jobs while the whites who formed the majority group did the white collar jobs. This analysis incorporates statistical data collected from the Statistical Bureau.

Purcell: Dido and Aeneas

Introduction:
Purcell’s opera is one of the classic works which includes singing of the highest level together with instrumentation which also shows the composer’s skill at high level opera production. The opera which deals with Ancient Greece is based on a libretto by Nahum Tate who adapted the story of Dido and Aeneas in Carthage in quite a masterful way also including parts which could be said to be tribute to marriage between two monarchs with an allegory to the present manage between Queen Mary and Prince William.
Purcell’s score is richly imbued with several fine ...

Introduction

Wind energy has been in use as far back as 3000 B.C., when sailors in Egypt utilized this energy to move their boats. Today, wind energy is hailed as an important source of energy and is tapped in various regions around the world. Its importance stems from two factors: (1) it is renewable and (2) it is a clean source of energy that does not generate environmentally harmful emissions. To harness wind energy, a wind turbine is used. A turbine converts the kinetic energy of the wind into rotary mechanical energy, which can then be converted to electrical energy (“Wind turbine,” ...
