5 dni temu · This simple formula generalizes to define moment of inertia for an arbitrarily shaped body as the sum of all the elemental point masses dm each multiplied by the square of its perpendicular distance r to an axis k. An arbitrary object's moment of inertia thus depends on the spatial distribution of its mass.

4 dni temu · The normal to the curve is the line perpendicular (at right angles) to the tangent to the curve at that point. Its equation can be found out by the point-slope form as the tangent's point of contact and slope will be known.
4 dni temu · The slope of the perpendicular line, \(m_{\text{perp}} = -\frac{1}{m} = \frac{b}{a}\). Using the point-slope form, \(y - y1 = m{\text{perp}}(x - x_1)\), the equation of the perpendicular line can be derived. Example Calculation. Given a line equation \(3x + 4y = 12\) and a point \((1, 1)\), the perpendicular line's equation is calculated as ...
