Put A Spring In Your Step

Step 2 Calculate

your personal spring constant, or k value by Hooke's Law:
F = -kx

Derive your F, or force, value from your weight.
For example, for a woman who is 125lbs, F = approx. 570 (125lbs / 56.7 kg x 10.8 m/s2)

x is the distance that the spring compresses, which will be approximately 3/4" (or less)

Plug it into the formula, and you have your k value. Use this value to search for your personal coil spring.

Isn't it 9.8m/s2 not 10.8m/s2?

You bet.

I believe it is.
