I have a part that needs about five lbs. of spring force over a
movement of 0.140"
The only design that will work in this space is a flat stock spring
3/8" wide. Think of a diving board sticking out. The force on the end
of the board needs to be 5 lbs over this 0.140" movement. Not exactly
constant but close.
I can select several material thickness from .035 to .062, could
double or triple layers.
I can easily change the length of the spring from near 0 to over two
inches with solid mounting behind.
I can change the amount of preload by adjusting the height of the
OK, what amount of length and deflection gives about 5lb. force with
these material choices? Must be some kind of calculator someplace.
