OK, we have a better picture now. You are supporting a nominal 4x4 post on either end of the ridge beam. One option is to support the base of the post on a plywood floor, presumably blocked in some fashion. Before you do it this way, you should carefully review the American Plywood Association (APA) guidance on direct support of posts over plywood, document rr135.pdf, available free from the APA website.

The type of loading you would have is called punching shear, for the reason that the likely mode of failure is that the post would punch through the plywood. Of course, if you install solid blocking underneath the load point of the post, this analysis does not apply. However, it may not be possible to install such blocking, and if you do, you then need to check the blocking for shear. But back to the pure plywood situation.

The actual punching shear area is computed by taking the perimeter of the post (14 inches in this case), multiplying by the effective thickness of the plywood (this comes from a table in APA, and is LESS than the actual thickness of the plywood). For example, 7/8 inch underlayment has an effective nominal thickness of .6 inches. You then take the actual load, which you said was 2,330 lbs, and divide by the punching shear area, and compare this result to the allowable stress in plywood.

Example: In your case, if your floor was 7/8 inch underlayment, your effective shear area would by 7x.6 = 4.2 square inches. The punching shear would be 2,330/14 = 166 psi. This would be unacceptable under APA guidelines for 16 inch on center joists.

Of course, you may have a double layer of floor, and you may be planning to install support blocking, and you probably don't have 7/8 inch thick plywood. I am simply pointing out that supporting a post with a substantial load requires careful detailing of the connections.
