For this paper I would like to explore the different methods of moving a piano (because I play the piano regularly) and the physics involved for each method. Moving a piano is a prime example of the impact of manipulating Newtonian physics to our advantage, because pianos are so heavy that without our knowledge of forces and work, it would be extremely difficult to transport them. The first method I would like to explore is the method of using a pulley to lift a piano from the floor onto a higher surface, such as into a truck or onto the 15th floor of a building (as seen in many cartoons). Here, a few factors are important. First, the type of pulley is important. A fixed pulley, for example, would not be ideal for this procedure because …show more content…
As you can surely visualize, an inclined plane with a tiny slope (e.g. 10 cm vertical/m horizontal) would have to be ridiculously long (10 m!) in order to move the piano up a full meter. The advantage of the decreased force is counterbalanced by an increased distance needed to raise the piano. This decreased efficiency is due to the concept of work. Work in physics is defined as the force on an object multiplied by the distance or movement of the object, or W=F*d (Studios). In both these methods of moving a piano, the Force applied by the person (or motor) on the object is decreased to make movement less strenuous; however, the work needed to move the piano to where it needs to go has not changed. Consequently, the distance of the movement must increase to compensate the decrease in force. In summary, simple machines like pulleys and inclined planes are very useful in making moving heavy objects like pianos possible. However, these simple machines are not very efficient. In decreasing the force needed to move the object, they increase the distance (and ostensibly time) needed to move such objects to the desired location. The most favorable way to move a piano, then, would be to have a strong motor with just enough force to move a piano up a ramp or to pull the ropes through a pulley system. This system provides a balance of both distance and
Do you ever have one of those days when you remember your parents taking away all of your baseball cards or all of your comic books because you got a bad grade in one of your classes? You feel a little depressed and your priced possession has been stolen. This event is the same as August Wilson’s, The Piano Lesson. The story is about a sibling rivalry, Boy Willie Charles against Berniece Charles, regarding an antique, family inherited piano. Boy Willie wants to sell the piano in order to buy the same Mississippi land that his family had worked as slaves. However, Berniece, who has the piano, declines Boy Willie’s request to sell the piano because it is a reminder of the history that is their family heritage. She believes that the piano is more consequential than “hard cash” Boy Willie wants. Based on this idea, one might consider that Berniece is more ethical than Boy Willie.
Ballet is an athletic art form that utilizes muscle control, flexibility, and physical strength. It requires extreme discipline from the dancers and takes an extreme amount of mental concentration. This discipline causes dancers to have success throughout life and specifically in academic studies. There are many ways that dance can affect the success of a person’s life; however, there are two in specific that make dancers generally more successful. To begin, ballet causes dancers to be self-motivated workers; dancers cannot rely on others to push them to be better, but must have the drive within themselves.

The elevator tilts down or up on a horizontal tail surface leading to an increased or decreased lift on the tail. An aircraft’s nose is tilted down or up.
The first thing my group did was confirm our method of taking data and who would be doing it as well as defining out independent and dependent variables. Since we would be directly controlling the net force we made that our independent variable which left the acceleration as our dependent variable because it was a factor that varying as a result of our net force. We weighed our cart with every single mass in it along with the string and the hook which turned out to be 1.97kg. We did not add anything else to our system after this to keep the mass of the whole system constant. Our setup was like this: a ramp was sitting on top of the table, parallel to it so it had no slant. On one end of the ramp, a pulley was attached. On the other side of the ramp, a motion sensor was set up so it faced directly down the path of the
In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a four-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.
Woodworkers contribute to the beauty and variety of the wooden products that surround us. Some woodworkers are employed in primary industries, meaning that they transform raw logs into a usable form of wood to sell to manufacturers or the public. Woodworkers can also be found in secondary industries, manufacturing finished products such as wooden toys, beds, dressers, moldings, and window frames. Many woodworkers have to read blueprints or drawings of a finished product, Measure the materials and operate the machines that cut and shape the wood. They also use hand tools to be more precise. Woodworkers need to use many different types of machines. From manual to almost fully automatic. The increase in computerized machinery has increased the productivity and precision, as well as the demand for workers with computer knowledge.
This article by Jacques Ellul on Techniques is very fascinating. The writer discusses of machines and its relationship with technique which has been described nicely. Technique is a way of doing something that fulfills a goal or an aim, in an organized manner. It is an art to do the work in a very meaningful and efficient way to reach the best results. Early civilizations have seen the man growing up in many aspects, this approach and ability to invent new things is called ‘technique’.
We ran into Newtons First Law, which claims that an object resists change in motion, as the marble rolled down the floor it didn’t stop until it was acted against by friction. As we moved on, Newtons Second Law came into play when we were creating our lever as we need a ball that would roll down with enough acceleration that it could knock down the objects. Newton’s second law claims, that F=MA. So, we choose a golf ball since it would have more mass than a rubber ball, but it would have less acceleration when the lever was started. This way, it would knock the upcoming objects. Newtons Third Law claims that every action yields an equal and opposite reaction. This is proven in our Rube Goldberg Machine when the small car was rolling down the tracks as the wheels pushes against the track making the track move backwards. The track provides an equal and opposite direction by pushing the wheels forward.
Have you ever wondered how the modern piano came to be? Although few people consider it, the history and developments in the manufacture of pianos is very important to the creation of the music we have today. The limitations and characteristics as well as the advancements of the early pianos affected the music that composers wrote for those instruments. We cannot fully understand the music unless we understand something of the instrument it was written for, so, with that in mind, it would be helpful to go over the early history of pianos.
Over the Summer I learned a valuable lesson with piano. Many would think it is practice makes perfect, however that is not the case. In my case it is, grow some confidence and be brave. Although I am loud, talkative,and helpful, behind my personality is another face. This face is quiet and shy, for over the years, it grew a glass cage over my heart. It was, and still is, hard to keep in the tears whenever I get yelled at. I get yelled at for not reading the notes right, why I keep messing up, and if I actually practiced during that entire week. I know my teacher, Mrs. Thuy doesn’t mean to hurt me, it’s just how I am. I remember how some weeks I cried after Mrs. Thuy left the room after yelling at me. But this year's auditions is an audition
Risers fall under the category of motorized recliners for uplift and recline. . Riser recliners possess electric motor within, which are connected to wall socket .The requirement for the chair is that it requires ample space and positioned away from walls. Two types of motors are used for making riser recliners either a single motor or a dual motor. Single motored recliners as the name suggest has a single motor which is used for reclining and rising of chair. In case of dual motor recliners, one motor controls the chair and the other functions the footrest. Remote options are are available for riser recliners
Material selection is among one of the most important aspects that must be taken into account before any hanging mechanism is produced. This is because material plays an important role in determining the suitability and durability of the hanging mechanism design. Nowadays, more advanced materials have been used to replace conventional materials because advanced materials offer more advantages (Myrdal, 2009). For instance in furniture manufacturing, conventional material such as solid wood have been replaced with alternative lumber such as particle board, plywood, glulam, LVL or OSB because of their economic and production efficiencies.
Woodworking, a form of carpentry, has been around for centuries and overtime developed into a more modern art. Today people will mostly see woodwork in homes in the form of furniture and decorations, or even smaller things such as family heirlooms passed down by generations and simple crafts made by younger generations. The skill of woodworking, however, is not inherited but takes practice and years of experience to fully master. Even experienced woodworkers run into challenges sometimes. The key is to overcome that obstacle and find different ways to create something new from a piece of wood. It is interesting to see and go through the process in which a woodworker goes through
