Just carrying out calculations on a rear bicycle shock. Got my hands on one and intended to calculate spring stiffness and damping coefficent practically. Did it on the spring using a tensile tester and have come up with a spring stiffness value of 130000 n/m2. (750 lb/in). Problem when i dismantled the shock, the damper is not working any more. If anybody knows what sort of damping coefficent and average shock of this spring stiffness would use could u let me know? Doesn't need to be too accurate. Haven't time to locate another shock so hopeing for some help. Thanks in advance.
