Technicalities: Spring Rate and Preload In this case, the preload length is 35mm and the resultant preload force is 17.5kg at zero travel. In other words, with this 0.5kg/mm spring and a setting at 35mm preload, you would have to put more than 17.5kg force on the end of the fork tube to create any movement at all.

- The parameter m will represent the total mass on the spring.3. Place the meter stick vertically alongside the hanging mass. Measure the elongation ofthe spring and record it as x 1. Always be sure to measure starting at the same place, eitheron the table or on the clamp.4. Add a 50 g slot mass to the hook and record m 2 (150 g). Read the meter stick andrecord x 2.

ANSWER KEY These were used to plot the line on the graph. The slope of the line, ignoring loads of less than 2kg, was found to be 22.2 ± 0.2 kg/m. From Equation 1, we see that we need to multiply this quantity by g to calculate a value for the spring constant of k = 217.4 ± 1.8 N/m.

How to Calculate Spring Force k is a proportionality constant called the stiffness, and is specific to each spring. The minus sign is in front because the force that the spring exerts is a returning force, meaning that it opposes the direction of displacement x, in an effort to return the spring to its unloaded position. The formula is accurate only up to a point. 2  For large x it will not be accurate. 3  Displacement x in both directions will not necessarily effect the same magnitude of restoring force, e.g. if the turns of the spring's coil are tightly bound in the relaxed, equilibrium position.

Experimental uncertainty analysis Where T is the period, g is the gravitational acceleration of 9.8 m/s, and L is the length of the pendulum (this is the length from the middle of the washer to the end of the string).Weigh your washer and measure the length of the string.Plug these numbers into the formula to calculate the period.ou can change the length of your string to make the period 1 second. Now you have created your own stopwatch! One of the most important things to learn about the formula above is that it doesn't depend on how heavy your washer is! Next time you see a clock with a pendulum, take a close look at it.

How to Calculate a Spring Constant Using Hookeâs Law (k is called the spring constant, which measures how stiff and strong the spring is. x is the distance the spring is stretched or compressed away from its equilibrium or rest position.). The force exerted by a spring is called a restoring force; it always acts to restore the spring toward equilibrium.

- 1 You will need to measure the diameter of the holes in the winding cone (the collar that secures the spring to the metal shaft) to determine what size bar or rod to use. Most cones have a hole diameter of 1/2 inch.  Do not attempt to use any sort of tool as a substitute for the winding bars or steel rods.
