In this expression, m stands for the total mass of the blade and r stands for the distance in the radial direction where this mass resides. In this case, r will be location of the blade's center of mass in the radial direction. The blade mass and center of mass will be found later in the tutorial using ANSYS. We can however provide the results now for the sake of this calculation. The blade weighs 22,473 kg and its center of mass (X, Y, Z) is located at the coordinate (-14.232 m, -0.213 m, 0.160 m).  As you know, the blade is oriented so that the x-axis points along the radial direction of the blade. Plugging in these the relevant values in the radial force formula we obtain:
