A block of mass $m$ is suspended by different springs of force constant $k$ as in Figure 5.99. Let the time periods in the four positions be $T_{1}$ , $T_{2}$ , $T_{3}$ , $T_{4}$ . Then:

Options:

Answer:

Solution:

(i) and (ii): the effective stiffness is $k$ (pulley changes direction only), $T = 2 π m / k$ . (iii) and (iv): two $2 k$ springs act in parallel, stiffness $4 k$ , $T = 2 π m /4 k$ . So $T_{1} = T_{2}$ and $T_{3} = T_{4}$ .
