Moment of Inertia of a Semicircle Formula, Solid Plane |
||
| \( I_x \;=\; I_y \;=\; \dfrac{ \pi\cdot r^4}{8 }\) | ||
| Symbol | English | Metric |
| \( I \) = Moment of Inertia | \(lbm\;/\;ft^2-sec\) | \(kg\;/\;m^2\) |
| \( \pi \) = Pi | \(3.141 592 653 ...\) | \(3.141 592 653 ...\) |
| \( r \) = Radius | \( in \) | \( mm \) |
