The center of gravity of a body depends on its shape and size of the body. For example, in a sphere, CG is at the center. The CG of a body may not necessarily be within the body. For example, the CG of a ring does not lie in the material of the ring; it is at its geometric center.

Center of Gravity – Measurement along two horizontal axes in a single setup with better than +/-0.001 inch (0.025mm) accuracy for payloads weighing as little as 4% of machine capacity! Moment of Inertia – …

This moment measurement method is used in the KSR and SE8913 series of center of gravity measurement instruments. Accuracy of Center of Gravity Measurement. Depending on what you are trying to do, your requirement for accuracy will vary. For example, if you want to stack books on a table, you only need to know the center of gravity within a few ...

 — Remember that the center of gravity on the forklift will change depending on the load or momentum. If the center of gravity ends up outside the triangle, the forklift will tipover. Let's look at the center of gravity. An unloaded forklift's center of gravity is between the axle of the steer wheels at A and the drive wheels at B-C.
