Mechanical Engineering.: Manufacturing of brake disc

The manufacturing method used in production of brake discs is the metal casting process and to be more specific, it is the permanent mold casting process that takes place in the production of these brake discs that usually gives out a good surface finish for the end product.2.


If a new theory better explains and predicts a phenomenon than an old theory (i.e., it has more explanatory power), we are justified in believing that the newer theory describes reality more correctly. This is called an intertheoretic reduction because the terms of the old theory can be reduced to the terms of the new one.

Production Costs vs. Manufacturing Costs: The Difference

Production costs reflect all of the expenses associated with a company conducting its business while manufacturing costs represent only the expenses necessary to make the product.

Flowing Material Balance (FMB) Theory

This procedure, illustrated below, consists of a plot of p wf /Z, where p wf is the flowing sandface pressure at the wellbore vs. cumulative production. A straight line drawn through the flowing sandface pressure data and then extrapolated parallel from the initial reservoir pressure gives the original gas in place.

Construction Sand and Gravel Statistics and Information

Construction sand and gravel, one of the most accessible natural resources and a major basic raw material, is used mostly by the construction industry. Despite the low unit value of its basic products, the construction sand and gravel industry is a major contributor to and an indicator of the economic well-being of the Nation.


Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing.
