It can be used when discussing the reduction of weight in a product or material, often in contexts like engineering, manufacturing, or design.
Example: "The new design features a weight saving of 20%, making it more efficient for transportation."
Alternatives: "a weight reduction" or "a decrease in weight".
For bridges and cars, a weight saving is less important.
The platform's underpinnings provide a weight saving of about 200 pounds over the previous-generation León, the company said.
One achievement, which the new Golf shares with the A3, is a weight saving of about 100 kg compared with the sixth-generation model, an example of a trend towards lighter cars that is now gathering pace – the smaller Peugeot 208 and Renault Clio, for example, also weigh quite a bit less than the models that came before.
With a weight saving of 29.7%, the hollow shaft is experimentally found to have almost no influence on the volumetric efficiency, but to reduce the mechanical efficiency by 0.6 2.4%.
The results obtained from numerical analysis and experimental testing encouraged using particulate reinforced metal matrix composites for critical component steering knuckle with a weight saving about 55% when compared with currently used SG iron.
For the considered steel cable net structure a weight saving of 17% for a partial factor for prestress 1.35 is obtained.
That's a 6kg weight saving.
The study demonstrates that in addition to a significant weight saving, up to 30% increase of flutter speed for the composite wing box can be achieved by optimizing the fibre orientations of the wing skin and spar web laminates.
In the case of freighters, this means no crew – so there is an extra weight saving by getting rid of the life support systems and the windows.
In fact, if one would reduce the one to the other, the most probable outcome will be just a very modest weight saving, gained at a very high price.
A 2% weight saving for the pretension factor 1.0 versus 1.35 is obtained if the tensile surface including the membrane and the edge cables is considered separate from the primary structure.
