Trigonometry in Engineering Aerospace Engineering by Jigar Patel &
Bette Anne Stroud Trigonometry Trigonometry is the study of the relationships between the sides and the angles of triangles Real world applications are seen in many fields, but particularly in the many aspects of Engineering Engineering: Is an application of scientific, economical, social, and practical knowledge. Is used to design, build, and maintain various structures, machines, systems, and processes. Once all of the measurements of the triangle (structure) are known, the engineer can begin building and defining the scope of the project he or she is undertaking. Many different types of Engineers use Trigonometry. Various Engineering jobs that use Trigonometry Civil Engineering Mechanical Engineering Aerospace engineering is the primary branch of engineering concerned with the research, design, development, construction, testing, science and technology of aircraft and spacecraft. What is Aerospace
Engineering? The main way trigonometry plays a role in Aerospace Engineering is when flying an airplane and using a manual flight computer to calculate the component of wind correction needed to maintain a constant track across the ground. How is Trigonometry used in Aerospace Engineering? Flight computers are used during flight planning (on the ground before takeoff) to aid in calculating fuel burn, wind correction, time en route, and other items. In the air, the flight computer can be used to calculate ground speed, estimated fuel burn and updated estimated time of arrival. The back is designed for wind correction calculations, i.e., determining how much the wind is affecting one's speed and course. Manual flight computer True Ground Speed Wind Correction Angle Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, and buildings. Civil Engineering Trigonometry is used in the building plans. It is used in calculating dimensions, such as height and width, and angles. Trigonometry is used in building scale models and the actual building, or roads, bridges, etc.. Trigonometry can also be used in determining the structural integrity of a structure. How is trigonometry used
in Civil Engineering? An example of Trigonometry
used in Civil Engineering Finding the height using a known measurement and angle Mechanical engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. Mechanical Engineering Trigonometry is a basic mathematical method that is used in a wide array of applications in Mechanical Engineering. In particular it is used in ratios, force triangles, displacement, and dimensional studies. How is trigonometry used in
