If I'm ×4 strong and my club is ×4 heavy, do I hit you with ×16 force?

If you are 4 times stronger than you will do twice the damage.

ST 10 (20) vs ST 20 (80). ST 20 is 4 times stronger, and the damage should be based on the square root of that, which means the damage should be 2 times what ST 10 can do.

with a more massive weapon, maybe a little more than that.
