An underformed spring with the spring co...

An underformed spring with the spring constant k has length `l_(0)`. When the system (Fig.) rotates at an angular

velocity `omega`, the weight with mass m causes an extension of the spring. Find the length `l` of the rotating spring.

Text Solution

Verified by Experts

The correct Answer is:
`l=(l_(0))/(1-m omega^(2)//k)`
The elastic force `F_(el^(-)) k(l-l_(0))` imparts a contripetal acceleration to the weight.
