The idea of the moment is commonly used in door hinges, foldable ladders, etc. Mathematically, the moment is the product of force and perpendicular distance. The Area of the shape is but one way of understanding the dimensions of the shape, the other is the Volume.Īlso, the Moment of a material is the measure of the tendency of a material to rotate about a point or along an axis, as a result of the force acting on one part of the material. To understand an object’s Moment of area, you need to first understand the terms that make them up, which are ‘Moments,’ and ‘Area’.įirstly, Area is the total value of the dimensions of a plane surface, which includes triangles, squares, and circles, and also solid shapes like spheres, cubes, cylinders, etc. The First Moment of Area plays a Crucial Role in Building Construction. For clarification, these materials include steel, wood, textiles, plastics, concrete, alloys, other geological, and biological materials, etc. In addition, the behavior of these physical materials includes motion, deformation, and other physical activities that the materials would undergo. Continuum mechanics look into the behavior of solid and physical materials and their resultant attitude when acted upon on forces, phase changes, and temperature changes, and other physics-related elements. The concept of Moments of Area has its roots deep in Solid mechanics, which in turn is a branch of Continuum mechanics. Last but not least, the scope of our discussion has been limited to the peripherals and we would do our best to provide you with appropriate platforms to read up and discover more. But we’ll do our best to make them easier to understand.Īnd for our readers with an understanding of the sciences, most of our contents have been diluted to make them easier to follow.
The concept of the first moment of area is highly scientific and contains terms and methods that may be unfamiliar. However, a fair warning to readers with little background in science. Professions like civil, mechanical, nuclear, aerospace, and aeronautic engineers, all heavily depend on the concept of the first moment of area to carry out some of their very exclusive function. The reinforced frame of an aircraft body and sea vessel are some of the few critical CAD-related activities that employ the concept of the first moment of area.
