WebMoment of inertia, denoted by I, measures the extent to which an object resists rotational acceleration about a particular axis, it is the rotational analogue to mass (which determines an object's resistance to linear acceleration ). The moments of inertia of a mass have units of dimension ML 2 ( [mass] × [length] 2 ). WebThus for the rectangle containing the entire section, the second moment of area is given by I = bd3 /12 = (50 × 70 3 )/12 = 1.43 × 10 6 mm 4. Each of the ‘missing’ rectangles will have a second moment of area of (20 × 50 3 )/12 = 0.21 × 10 6 mm 4. Thus the second moment of area of the I-section is 1.43 × 10 6 − 2 × 0.21 × 10 6 = 1.01 × 10 6 mm 4.
