How about the Y-Y moment of inertia in the form of hot rolled channel steel Iy?
Among them, H, B, D and T are the corresponding parameters on the standard. B leg root thickness, a thickness of leg point or T = (a + b) divided by 2, R for leg root radius, R leg tip radius, Z standard centroid value, ^2 said in front of the results in parentheses square, ^3 cube, X said after the power multiplied by the other the local sign is omitted, said by slash.
The method of superposition of moments of inertia: the moment of inertia of multiple rectangles plus the moment of inertia of the four surfaces of the cornersEach of the deformed moments of inertia is equal to the sum of the two triangular moments of inertia and the sectorial moments of inertiaThe sectorial moment of inertia is used in integral calculus, and the examples of advanced mathematics are taken at random.
Moment of inertia (Ix or Iy) = area X the square of the centroid to the axisRadius of inertia (IX or iy) = the area divided by the moment of inertia, then taking rootInertial product (Ixy = area multiplied by centroid to two axis distance)Coefficient of flexural cross section (Wx or Wy) = moment of inertia divided by the distance from the farthest point of the coordinate axis on the cross section
