Δ X F Sean Daehn Spring Lab Report Purpose: to develop a conceptual and mathematical model for the relationship between the force and stretch of a spring. Apparatus: Procedure: We used a stand that a clamp went on. Then we clamped a rod on. We put our spring on the end of the rod. Then we put a mass on the end of the spring and measured how much the spring stretched. We repeated this process ten times. Data: Stretch (m) Mass (Kg) Weight (N) .01 .1 .98 .02 .2 1.96 .03 .3 2.94 .04 .4 3.92 .05 .5 4.90 .06 .6 5.88 .07 .7 6.86 .08 .8 7.84 .09 .9 8.82

Sean Daehn .1 1 9.8 Conclusion: Relationship: Direct Relationship Model: (98 N / m ) ΔX + f 0 F=K ΔX+f 0 Slope: K=Spring Constant=Stiffness Y Intercept = minimum force required to start stretching the spring.

Unformatted text preview: Explanation: the relationship between the force and stretch is linear, if you apply a larger force, you get a larger stretch. Force is equal to the spring constant times the stretch plus the load force. The slope is equal to the spring constant which is equal to the stiffness of the spring. How hard is it to stretch? The y intercept is the minimum force required to start stretching the spring. Our y intercept went through the origin which is abnormal but it happened because our slope was 98 N / m which was high it was supposed to be around 75 or 80. Sean Daehn...
