Four massless springs of constant $2 k$ , $2 k$ , $k$ and $2 k$ are attached to a mass $M$ on a frictionless plane as in Figure 5.125 (two $2 k$ in series on the left, $k$ and $2 k$ in parallel on the right). If $M$ is displaced horizontally, the frequency of the system is:

Options:

Answer:

Solution:

Left series pair: $\frac{2 k \cdot 2 k}{4 k} = k$ . Right parallel pair: $3 k$ . Both act in the same sense: $k_{e q} = 4 k$ , $f = \frac{1}{2 π} 4 k / M$ .
