Question
Coil springs are widely used in industry. Those used in scientific instruments must be manufactured to exhibit consistent performance. One important property of a spring is its force constant. As the quality control manager of a coil spring manufacturer, you are examining a coil spring made by your company that compresses 0.0360 m when a mass of 195 kg is placed on it. Calculate the force constant k. Your customer specifics that the springs used for its mass scales must fit within 5% of k = 55210 Mm. Shipping products that have been known to fail specification requirements can open your company to civil or criminal charges, or both. Knowing this, would you accept or reject this spring? Accept Reject In the list below, choose the specifications that coil springs often must meet. Temperature dependence of the force constant. Range of expansion in which the force constant remains valid. Range of compression in which the force constant remains valid. Size of the spring (height and width).Explanation / Answer
1) k = force/displacement = Mg/displacement= (195*9.8)/0.036= 53083.33 N/m ( where M is mass, g= gravity acceleation)
2) I will reject the spring which is not meeting the specifications.
3) Range of expansion in which force constant remains valid.
Range of compression in which force constant remains valid.
