TASK: Turning a Mild Steel Bar.
We were each given a mild steel bar to work into the shape shown in
the drawing found on the following pages, to do this we used the
Turning Lathe in the workshop, but before we could start some
measurements had to be taken. This meant using a micrometer to
determine the diameter of the bar to begin with.
A micrometer allows a measurement of the size of a body. It is an
extremely accurate piece of apparatus. The Thimble is rotated, causing
it to move right or left. It is connected to the right-hand Measuring
Rod. The measured size of the mild steel bar is the distance between
the two measuring rods when they are just in contact with the sides of
the bar.
Because of the mechanical advantage due to the fine pitch of the screw
threads that move the thimble and the right-hand measuring rod, it is
easy to use enough force in closing the rods on the object being
measured to deform either the rods or the object. A Friction Screw is
used, which applies just enough torque to rotate the thimble so it
doesn’t deform the bar or the measuring rod. This Friction Screw is
found at the end of the thimble.
The reading of the micrometer is outlined in the diagram found on the
following pages of this document.
The First part of the task was to give one end of the bar a smooth
finish, this was done by fixing the bar into the lathe using the chuck
key, then positioning the tool piece as near to the centre of the bar
as possible then shaping off a small amount of material, it is
important to get the tool piece in the correct position as if it is
too high or too low it will miss part of the material. A Cutting speed
was determined by the diameter and material of the bar then equating
this figure to one of the speeds attainable by the lathe. This turned
out to be 370 RPM for this machine selecting the relevant gears.
As the diameter of the bar reduces, the cutting speed will need to
increase.
Once one end has been smoothed, the bar was turned round and worked on
from the other end, the first task was to remove 75mm in length with a
resulting diameter of 22mm, this was done not all in one go as you had

“The Industrial Revolution was another of those extraordinary jumps forward in the story of civilization” (Stephen Gardiner). One of the major parts of the industrial process has to do with metal production. Welding has been incorporated into the framework of metalworking. Welding dates back to the middle ages where forge welding processes were used to make tools and weapons, commonly known as blacksmiths. It is known that the Egyptians used forms of welding to make gold tools, jewelry, and decoration. During the 1800’s a new process was formed by using carbon electrodes to form an arc. This was done by Sir Humphrey Davy, which carried on to become Carbon Arc Welding and the most used process during the late 1800’s. As time evolved so did the

Fabrication at the factory utilizes a mix of robotics and manual labor to produce the body of the V-Rod. Robots that are designed to cut pipe are capable of completing a single operation within 3 seconds. Other fabrication robots utilize 1800 watt lasers that can perform cutting operations at the rate of 100 inches per minute. Where robotics can be used to perform high speed cutting and welding operations, skilled workers are a...
(Johann Chrysostom) Wolfgang Amadeus Mozart was born in Salzburg, Austria on January 27, 1756 to composer, violinist, and theorist Leopold Mozart and his wife Maria Anna (Sadie 276). Wolfgang was the ultimate definition of a child prodigy. He mastered one of his sister’s music books at the age of four and wrote his first compositions, Andante and Allegro K1a and 1b, at only five years old (277). The public first witnessed young Mozart’s talent when he performed a dancing role in Sigismundus Hungarie rex at Salzburg University in September of 1761 (277). Mozart flourished in the spotlight and began to tour Europe with his father and sister, Maria Anna (affectionately referred to Nannerl), in September of 1762 (277). Both children were extremely talented musicians and they often performed for the courts or gave public concerts (277). The family returned home to Salzburg ...
Mozart’s The Marriage of Figaro brought new life to opera in the classical period. This feat is one we can only come to expect of Mozart. His mastery of this style of opera sealed his place in history in the opera genre. His operas would continue to be masterful works throughout the period, and his successes were duly deserved. The Marriage of Figaro is still performed to this day around the world and is one of the most performed operas of all time.

Probably the greatest genius in Western musical history, Wolfgang Amadeus Mozart was born in Salzburg, Austria, Jan. 27, 1756, the son of Leopold Mozart and his wife, Anna Maria Pertl. Leopold was a successful composer and violinist and assistant concertmaster at the Salzburg court, whose archbishop, Sigismund von Schrattenbach, encouraged the activities of Leopold and his remarkable children.
Mozart was born in Salzburg, Austria, the son of composer, musical author, and violinist, Leopold Mozart and his wife, Anna Maria Pertl. His given names were Johann Chrysostom Wolfgang Theophilus, the last of which is Gottlieb in German, and Amadeus in Latin. He used Wolfgang and Amadeus in his signature, so he is generally known by these two names.

Johann Chrysostom Wolfgang Amadeus Mozart baptized as Johannes Chrysostomus Wolfgangus Theophilus Mozart born January 27, 1756, in Salzburg Austria. Mozart was an esteemed composer, widely recognized as one of the greatest composers in the history of Western music. Unlike other composers in musical history, he wrote in all the musical genres of his day and excelled in every one. His taste, his command of form, and his range of expression have made him seem the most universal of all composers; yet, it may also be said that his music was written to accommodate the specific tastes of particular audiences. His father, Leopold was the author of a famous violin-playing manual which was published in the year of Mozart’s birth. His mother, Anna Maria Pertly, was born of a middle-class family active in local administration; Mozart and his sister Maria Anna were the only two of their parents’ seven children to survive. Mozart was extremely talented at an early age his father considered him the miracle of Salzburg, his early life and two of his biggest masterpieces are the three topics that will be discussed in this paper.
This paper discusses Mozart's life, his compositions and his importance to the world and the world of music. It explains how Mozart's music is still some of the most popular classical music played today and his life is still studied because his music is so well known and liked.
Mozart’s use of melodic contour and repetitive rhythmic motives make this piece feel very connected throughout. He begins with a two eighth note followed by two quarter note pattern. This pattern is repeated twice more until finally at measure four a new melodic and rhythmic motive is introduced. At measure four a retardation occurs using a half note to delay the resolution to the quarter note, drawing out the resolution as much as possible to create a sense of relief upon arrival. This pattern of three measures of motive “A” followed by...
