Music has been used throughout the ages as a supplementary form of communication, a way to stimulate the mind, as well as for pure entertainment value. Because music has become such a vital component to our society, it should come as no surprise that humans have been working for millions of years to create environments more conducive to musical performance. Science has lent itself to the study of acoustics to accommodate this need for such an environment. This has become a continuous effort because of the nature of music and the act of listening. Sound quality is a subjective assessment. What we consider positive aspects of a sound varies from person to person and also varies over time periods in our history. Design criteria needed to evolve to accommodate these trends. Aspects of architectural design have also developed to accommodate for the changing purposes for these structures; the ancient Greeks and Romans needed a way to project the voice for performances of the great tragedies, whereas now we are concerned with performance of popular music and theatre. To fully understand and appreciate the design elements of these structures, a basic knowledge of physics, materials science, and architectural design is necessary. One of the most essential of these topics is the physics involving the path of a sound wave from source to receiver. An enclosed space, like a theatre or a concert hall, provides an infinite number of different paths for the longitudinal sound wave to take in traveling from source to receiver. Depending on the properties of a surface, a sound wave will experience reflection, diffraction, diffusion, or absorption when contacting the surface.

Integrated software controls the process and communicates the contents of the CD to the computer. Robotics is the application of mechatronics to create robots, which are often used in industry to perform tasks that are dangerous, unpleasant, or repetitive.

These robots may be of any shape and size, but all are preprogrammed and interact physically with the world. To create a robot, an engineer typically employs kinematics to determine the robot's range of motion and mechanics to determine the stresses within the robot. Robots are used extensively in industrial engineering.

They allow businesses to save money on labor, perform tasks that are either too dangerous or too precise for humans to perform them economically, and to ensure better quality. Many companies employ assembly lines of robots, especially in Automotive Industries and some factories are so robotized that they can run by themselves. Outside the factory, robots have been employed in bomb disposal, space exploration , and many other fields. Robots are also sold for various residential applications, from recreation to domestic applications.

Main articles: Structural analysis and Failure analysis Structural analysis is the branch of mechanical engineering and also civil engineering devoted to examining why and how objects fail and to fix the objects and their performance. Structural failures occur in two general modes: static failure, and fatigue failure. Static structural failure occurs when, upon being loaded having a force applied the object being analyzed either breaks or is deformed plastically , depending on the criterion for failure.

Fatigue failure occurs when an object fails after a number of repeated loading and unloading cycles.

Mechanical engineering

Fatigue failure occurs because of imperfections in the object: a microscopic crack on the surface of the object, for instance, will grow slightly with each cycle propagation until the crack is large enough to cause ultimate failure. Some systems, such as the perforated top sections of some plastic bags, are designed to break.

If these systems do not break, failure analysis might be employed to determine the cause. Structural analysis is often used by mechanical engineers after a failure has occurred, or when designing to prevent failure.

Engineers often use online documents and books such as those published by ASM [29] to aid them in determining the type of failure and possible causes. Once theory is applied to a mechanical design, physical testing is often performed to verify calculated results.

Structural analysis may be used in an office when designing parts, in the field to analyze failed parts, or in laboratories where parts might undergo controlled failure tests.

Thermodynamics and thermo-science[ edit ] Main article: Thermodynamics Thermodynamics is an applied science used in several branches of engineering, including mechanical and chemical engineering. At its simplest, thermodynamics is the study of energy, its use and transformation through a system. As an example, automotive engines convert chemical energy enthalpy from the fuel into heat, and then into mechanical work that eventually turns the wheels.

Thermodynamics principles are used by mechanical engineers in the fields of heat transfer , thermofluids , and energy conversion. Mechanical engineers use thermo-science to design engines and power plants , heating, ventilation, and air-conditioning HVAC systems, heat exchangers , heat sinks , radiators , refrigeration , insulation , and others.

A technical drawing can be a computer model or hand-drawn schematic showing all the dimensions necessary to manufacture a part, as well as assembly notes, a list of required materials, and other pertinent information.

Drafting has historically been a two-dimensional process, but computer-aided design CAD programs now allow the designer to create in three dimensions. Optionally, an engineer may also manually manufacture a part using the technical drawings.

However, with the advent of computer numerically controlled CNC manufacturing, parts can now be fabricated without the need for constant technician input. Manually manufactured parts generally consist spray coatings , surface finishes, and other processes that cannot economically or practically be done by a machine. Drafting is used in nearly every subdiscipline of mechanical engineering, and by many other branches of engineering and architecture.

Cavanaugh , Gregory C. Tocci , Joseph A. A widely recognized, comprehensive reference to acoustic principles for all concerned with the built environment, Architectural Acoustics, Second Edition provides design professionals with up-to-date information on basic concepts, acoustical materials, and technologies for controlling wanted or unwanted sound within and around buildings.

Written by a team of internationally recognized experts and experienced consultants, this Second Edition covers fundamental acoustic principles, design criteria, acoustical materials, control strategies, and methods for a wide variety of building types, including educational, healthcare, recreational, residential, commercial, industrial, and transportation facilities.

Particular attention is given to places for listening and performance such as theaters, churches, concert and recital halls, outdoor arenas, classrooms, multiuse auditoria, libraries, music practice and rehearsal rooms, recording and broadcast studios, sports venues, home theaters, and other spaces that people meet to communicate and enjoy performance.

With fundamental conceptual understanding of basic acoustical principles provided by Architectural Acoustics, Second Edition, building designers can confidently create aesthetically and aurally pleasing spaces, while avoiding problems that could be very costly, if not impossible, to solve later.
