If you have two compression springs and everything is the same except number of active coils, which will take more force to compress? The one with more coils or one with less coils?
Take for example:
Spring 1= 6 inch long, 1in outer diameter, 0.1" wire diameter, 10 active coils - compress 2 inches
Spring 2= 6 inch long, 1in outer diameter, 0.1" wire diameter, 8 active coils - compress 2 inches
Everthing I find (spring creator tools, equations, etc) says that spring 2 would take more force to compress, although I am not understanding why and feel spring 1 with more coils should take more force to compress? What logic / theory am I not understanding?
(equation - k = gd^4/(8nD^3) where n= number of active coils
