A forced-air heating system uses a system of ____ air ducts to deliver warm air to the conditioned spaces.
If too much amplification is applied to an audio signal, waveform distortion can occur causing a phenomenon called _____.
Answer: clipping
Explanation:
Dislocations have a major effect on the plastic deformation of metals, but do not play a major role in the mechanical behaviour of ceramics. Why?.
Dislocation often plays a major role in plastic deformation of the material because material can be increased by plastic deformation. The number of dislocation often brings about motion depicts plastic deformation.
Dislocations are gotten and move when a stress is applied. The motion of dislocations allows slip and then plastic deformation takes place.
The dislocations often move along the densest planes of atoms in a material. This is due to the fact that the stress needed to shift the dislocation rises with the spacing between the planes.
Dislocations play an essential role in the plastic deformations of crystalline materials as they hinder the synchronized breakage of bonds between atoms in materials.

why is it important to follow the engineering design process before building a prototype
It is crucial to adhere to it since it provides a clear plan for how to identify the best solution to the issue in the most efficient manner.
You can experience your concept becoming real for the first time by creating a prototype. You can interact with, touch, and even destroy a prototype.
Why is it important to follow the engineering design process?Students that pursue careers in engineering and adhere to the steps of the design process are better able to think creatively because there is no one "correct answer." Through testing and ongoing improvement, engineers are encouraged to develop their own open-ended designs.
A working model of a solution is called a prototype. It is typically constructed using different materials than the final product, and it is typically less polished. A crucial stage in creating a final solution is creating a prototype, which enables the designer to test how the solution will function.

Which of the following best describes maintenance?
A) Making repairs as directed by a pinpoint test
B) The act of keeping a vehicle in good operating condition
C) servicing items that are worn
D) performing the service needed to fix a concern
Answer:
Equipment Reliability and Maintenance
SUBSTANTIAL CAPITAL investments, in the form of facilities and equipment, are required for manufacturing almost all goods of economic significance. The productivity of these investments is a fundamental element of competition among companies and nations. Events that slow or interrupt the manufacturing process or degrade the product impair the competitiveness of a manufacturing enterprise.
The term equipment reliability and maintenance (ERM) encompasses not only equipment, such as machines, tools, and fixtures, but also the technical, operational, and management activities, ranging from equipment specifications to daily operation and maintenance, required to sustain the performance of manufacturing equipment throughout its useful life. This chapter addresses all causes of diminished or degraded output. The panel considers ERM to be a significant factor in the competitiveness of manufacturing firms, an assessment supported by the case studies in the section on present practice (pp. 57-63).
Historically, the evolution of ERM can be traced from breakdown maintenance and repair to preventive maintenance to predictive maintenance. Breakdown maintenance and repair is the after-the-fact restoration of failed equipment. Preventive maintenance is the systematic servicing of equipment to reduce the possibility of failure. Predictive maintenance, in use in U.S. industry for only four or five years, is usually understood to involve the use of computer software to detect conditions that might eventually lead
