A spring has spring constant $k$ and $l$. If it cut into piece spring in the proportional to $\alpha : \beta : \gamma $ then obtain the spring constant of every piece in term of spring constant of original spring (Here, $\alpha $, $\beta $ and $\gamma $ are integers)
Suppose length of $\alpha, \beta$ and $\gamma$ are $l_{1}, l_{2}$ and $l_{3}$ respectively and total length $l=\alpha+\beta+\gamma$
$=l_{1}, l_{2}, l_{3}$
$\therefore l_{1}=$ spring constant of $\alpha$ length
${l}k_{1}=\frac{k l}{l_{1}}=\frac{k(\alpha+\beta+\gamma)}{\alpha}$ $l_{2}=\text { spring constant of } \beta \text { length }$ $k_{2}=\frac{k l}{l_{2}}=\frac{k(\alpha+\beta+\gamma)}{\beta}$ $\text { and } l_{3}=\text { spring constant of } \gamma \text { length }$ $k_{3}$=$\frac{k l}{l_{3}}=\frac{k(\alpha+\beta+\gamma)}{\gamma}$
An ideal spring with spring-constant $K$ is hung from the ceiling and a block of mass $M$ is attached to its lower end. The mass is released with the spring initially unstretched. Then the maximum extension in the spring is
In figure $(A),$ mass ' $2 m$ ' is fixed on mass ' $m$ ' which is attached to two springs of spring constant $k$. In figure $(B),$ mass ' $m$ ' is attached to two spring of spring constant ' $k$ ' and ' $2 k$ '. If mass ' $m$ ' in $(A)$ and $(B)$ are displaced by distance ' $x$ ' horizontally and then released, then time period $T_{1}$ and $T_{2}$ corresponding to $(A)$ and $(B)$ respectively follow the relation.
A $1\,kg$ mass is attached to a spring of force constant $600\,N / m$ and rests on a smooth horizontal surface with other end of the spring tied to wall as shown in figure. A second mass of $0.5\,kg$ slides along the surface towards the first at $3\,m / s$. If the masses make a perfectly inelastic collision, then find amplitude and time period of oscillation of combined mass.
What is the period of small oscillations of the block of mass $m$ if the springs are ideal and pulleys are massless ?
Infinite springs with force constant $k$, $2k$, $4k$ and $8k$.... respectively are connected in series. The effective force constant of the spring will be
