Finding the spring constant of a rope

[QUOTE="jrmichler, post: 6856644, member: 638574"] The spring constant is the ratio of the load to the amount of stretch, so some how, some way, you need to measure how much the rope stretches under a known load. And to make it more interesting, you need to do it for a range of loads because the relationship between stretch and load is very likely not linear. Another thought: you can measure the actual peak loads when yanking a vehicle if you have access to a high speed accelerometer and data acquisition system. Knowing the mass of the pulling vehicle, and measuring the acceleration and velocity vs time, you can calculate the spring constant. Such a test will need an immovable load, such as a dump truck or big tree. The accelerometer will need about 1000 Hz bandwidth and the data acquisition system a sample rate of 1000 samples/sec.
