Question

what is the differernec between centre of mass and centre of rigidity

Answer 1

# the centre of mass is the mean position of the mass in an object.

# centre of rigidity is the stiffness centroid within a floor-diaphragm plan.

Answer 2

Answer:

For many objects, these two points are in exactly the same place. But they're only the same when the gravitational field is uniform across an object. Answer: The centre of mass is the point were the entire mass of the floor acts and centre of rigidity is the where the entire stiffness of the building acts.
