Shown below is the formula for the load inertial applied to a cylinder and rectangular parallelepiped.
1) Cylinder (including thin disc) 2) Thin rectangular
(rectangular parallelepiped)
3) Thin rectangular plate
(rectangular parallelepiped)
Point of rotation :
Center shaft
Point of rotation :
Point that goes through the
center of the gravity of the
plate and perpendicular to
the plate (same for when the
plate is thickened)
Point of rotation :
Perpendicular to the plate
and one-ended
