How to read the graph: only when the dimension of the load is “a” and “r”
[Example] When the load shape is w , a = 100 mm, and the load mass is 0.1 kg.In Graph (3), the point at which the vertical line of a = 100 mm and the line of the load shape w intersect indicates that the moment of inertia of the 1 kg
mass is 0.83 x 10–3 kg·m 2.
Because the mass of the load is 0.1 kg, the actual moment of inertia is 0.83 x 10–3 x 0.1= 0.083 x 10–3 kg·m 2.
(Note: If “a” is divided into “a 1a 2”, the moment of inertia can be obtained by calculating them separately.)

1How to read the graph: when the dimension of the load contains both “a” and “b”.
[Example] When the load shape is t , a = 100 mm, b = 100 mm, and the load mass is 0.5 kg.In Graph (3), obtain the point at which the vertical line of a = 100 mm and the line of the load shape t intersect. Move this intersection point to Graph (4), and the point at which it intersects with the curve of b = 100 mm indicates that the moment of inertia of the 1 kg mass is 1.7 x 10–3 kg·m 2.
Since the load weight is 0.5 kg, the actual moment of inertia is 1.7 x 10–3 x 0.5 = 0.85 x 10–3 kg·m 2.
