Engineering research refers to a systematic investigation or study that is conducted in order to develop new knowledge, improve existing technologies, and solve complex problems within the field of engineering. This type of research can involve designing experiments, collecting data through testing and analysis, developing mathematical models, and creating simulations to better understand how systems work and how they can be improved upon. The goal of engineering research is often to develop new products or processes that are more efficient, effective, and sustainable than existing ones. It plays a critical role in advancing the field of engineering by providing valuable insights into the behavior of materials, structures, and systems, as well as identifying areas for future innovation and development.
