"Resistant" typically means having the ability to withstand or oppose the effects of something, such as a force, substance, or condition, without being significantly affected or damaged.

Aerodynamics began as a science around the time of the Wright brothers' first manned flights. Since then, it's become important to the building not only of aircraft and automobiles but also of rockets and missiles, trains, ships, and even such structures as bridges and tall buildings, which often have to withstand strong winds. An aerodynamic vehicle is one whose design helps it achieve the greatest speed and most efficient use of fuel. But although we might casually call any sleek car design aerodynamic, true aerodynamics is practiced not by artistic product designers but instead by highly trained scientists, and many people's lives depend on their work.

Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion.

Engineering materials are substances or combinations of substances that are used in the design and construction of various engineering structures, components, and systems. These materials possess specific properties and characteristics that make them suitable for particular applications, such as strength, durability, conductivity, and corrosion resistance. Engineering materials include metals, polymers, ceramics, composites, and semiconductors, among others.

Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine.
