To save money. Also, in some cases, to save weight. For example, when building a plane, other things being equal, you want to make it as light as possible.
There are many types of materials engineers use to build walls. Three possible construction materials are wood, brick, and concrete.
Material Engineers bring valuable expertise in materials from mining to recycling. The job of a Material engineer is to produce, design and evaluate materials and their use.
Urban construction engineers are likely to use concrete, steel, and glass.

The least amount of anything
Vizio seems to give off the least heat and use the smallest amount of electricity.

Engineers use volume to determine the capacity and space requirements of various structures and materials. For example, they calculate the volume of concrete needed for foundations or the amount of fluid a tank can hold. Additionally, understanding volume helps in optimizing designs for efficiency, ensuring that systems function effectively within spatial constraints. Accurate volume measurements also play a critical role in safety assessments and regulatory compliance.
Chemical engineers play an incredibly important role in modern society. These engineers use chemistry to turn raw materials into products like plastics, petrochemicals, and medicine. They also play a key role in advancing waste management, pollution control, and resource conservation.
A magnifying lens
You would probably be talking about nuclear fusion, but it is not available for use and probably won't be for another 50 years, so it's an academic matter. For useful power, fission reactors are the only technology we have, and they all use uranium and produce similar amounts of fission products
Engineers commonly use materials with high strength-to-weight ratios, such as steel, aluminum alloys, and composites, to enhance the mechanical advantage of machines. These materials can withstand significant loads while remaining lightweight, allowing for more efficient design and operation. Additionally, lubricants and bearings may be employed to reduce friction, further improving performance and mechanical advantage. The choice of materials depends on the specific application and desired efficiency of the machine.
