In engineering practice, however, moment of inertia is used in connection with areas as well as masses. The term second moment is more proper than the term moment of inertia, since, logically, the latter should be used only to denote integrals of mass (see Sec.

The second moment of area is typically denoted with either an I. The second moment of area, or second area moment, or quadratic moment of area and also known as the area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. (b) 9.(d) 10.For a list of equations for second moments of area of standard shapes, see List of second moments of area. Question.10. The moment of inertia of a circular section about an axis perpendicular to the section isġ. Question.9. The moment of inertia of a circular section of base ‘b’ and height ‘h’ about an axis passing through its vertex and parallel to base is Question.8. The moment of inertia of a body is always minimum with respect to its The moment of inertia of a triangular section of base ‘b’ and height ‘h’ about an axis passing through its base is ………. times the moment of inertia about an axis passing through its C.G. Question.6. The polar moment of inertia of a circular section is about Similarly, the first moment of inertia about y-axis would be given by, Second Moment of Inertia: The moment of inertia calculated for an area is called the second moment of inertia. When force is applied to an object it resists, that’s inertia. It is stated in relation to a certain axis of rotation. The moment of inertia is a measurement of an object’s resistance to change in rotation. Hence the first moment of any area calculated about x-axis would be given by. Inertia: Moment of inertia: Inertia is defined as an object’s property or inclination to resist changes in its state of motion. The moment of inertia of a triangular section of base ‘b’ and height’h’ about an axis passing through its C.G. The first moment of inertia means the moment arm would be raised to a power of one. The moment of inertia of a circular section of diameter ‘d’ about its centroidal axis is given by The moment of inertia of a rectangle base ‘b’ and depth ‘d’ about the base will be Question.2. The unit of moment of inertia is (d) Depends upon the shape of the section Moment of inertia of the system about an axis passing through the centre of the disc & perpendicular to its plane is A. Definition: Polar Moment of Inertia the second area moment using polar coordinate axes J o r dA x dA y dA 2 J o I x I y Definition: Radius of Gyration the distance from the moment of inertia axis for an area at which the entire area could be considered as being concentrated at. (c) Depends upon the dimensions of the section Five particles of mass 2 kg are attached to the rim of a circular disc of radius 0.1 m & negligible mass. Area Moment of Inertia or Moment of Inertia for an Area - also known as Second Moment of Area - I, is a property of shape that is used to predict deflection.
