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 0.0710 m when a mass of 165 kg is placed on it. Calculate the force constant k. B) Your customer specifies that the springs used for its mass scales must fit within 5% of k = 23690 N/m. 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? C) In the list below, choose the specifications that coil springs often must meet.

Explanation / Answer

As per hooke's law

F = kx = mg

K = ( 165) (9.8)/ 0.0710= 22774.647 N/m

b) 23690 ( 5/100 ) = 1184.5

Acceptable range = 24874.5 to 22505.5

This coil fits within the specified range
