This set of Metal Casting Multiple Choice Questions & Answers (MCQs) focuses on “Effects of Friction and Velocity Distribution”. 1. The energy loss due to friction (Ef) in a circular conduit (on the basis of per unit mass) is given by___ a) Ef = 4fLv̅²/2D b) Ef = 8fLv...
In connection with questions on the wear of gun barrels, the frictional energy, which is also a major cause of this wear, plays an important role. This becomes especially important in case of lead-free and lead-reduced ammunition, which has become more and more popular over the last two de...
Furthermore, in some circumstances, slower rather than more rapid rates of OTM may be preferred to prevent unintended anchoring loss and post-treatment relapses. An alternative to all of these techniques is the development of novel biomaterials and innovative systems for the delivery of bioactive mo...
Our model specifies that the career friction caused by those differences is the cause of the performance loss. Proposition 1 : The relationship between individual attributes accrued from a prior career and post-transition performance is mediated by career frictions. Cognitive Fixedness as Moderator for...
Friction is an important subject for sustainability due to problems that are associated with energy loss. In recent years, micro- and nanostructured surfaces have attracted much attention to reduce friction; however, suitable structures are still under consideration. Many functional surfaces are present ...
This control is done by adding all the weight values together and multiplying them with a coefficient, which modifies the impact of the sum on the loss function. Typically, from the observations made on these considered functions, a value of 𝛼α lower than 0.005 corresponds to a small ...
It is such a universal phenomenon that rarely do two solid bodies slide over each other or even touch each other without measurable material transfer or material loss. Thus, coins become worn as a result of continued contact with human fingers; pencils become worn after sliding over paper; and...
The exporter then need not worry about loss or damage after the risk has passed to the importer; and the importer need not worry about insurance covering damages that occur before the risk passes to him. ??Customs duty ??There will be no dispute over the common practice that customs duties...
Furthermore, the loss of alloying element that occurred in fusion-based AM [103] does not occur in AFSD. 5.2. Microstructure During the rapid melting and solidification of fusion-based AM, the melt pool conducts heat into the substrate, forming a curved solid–liquid interface. During ...
