Spring constant of trampoline and cradle

Click For Summary
SUMMARY

The discussion centers on the spring constants of trampolines and cradles, specifically the relationship between spring constant (k), force (F), and extension (x) as defined by the equation k=F/x. It is established that trampolines require a low spring constant to allow for greater extension, enhancing bounce. In contrast, cradles necessitate a high spring constant to minimize extension, ensuring stability for sleeping infants. The confusion arises from the differing requirements of these two applications.

Spring constant of trampoline and cradle

Homework Equations


k=F/x

The Attempt at a Solution


I think a trampoline should have a low spring constant so that the extension is bigger. Is this correct? For cradle, in my opinion, it should have a low spring constant too so that the extension is bigger and the babies are able to sleep soundly. However, according to the answers given, the spring of a cradle has high spring constant. Does anyone know which one is correct? If yes, please kindly explain to me.

For a cradle the factor might be the period of the oscillations?
