Combination OF Springs|| Spring and string

Spring force and cutting OF springs

The period of oscillation of a mass M suspended from a spring of spring constant K is T. the time period of oscillation of combined blocks is

Three spring are connected to a mass m(=100g) as shown in figure. Given k=2.5Nm^(-1) . (a) What is the effecitve spring constant of the combination of spring constant of the combination of springs? (b) When mass m oscillates, find time period of its vibration.

Derive the expression for equivalent spring constant of (i) parallel combination of n- springs (ii) series combination of n- springs

A spring of force constant k is cut into two equal parts, and mass 'm' is suspended from parallel combination of the springs. Then frequency of small osciollations is

The spring constant of spring A is twice the spring constant of spring B . Each of the spring is cut into two pieces. First piece of spring A is (4//5) of the total length. Second piece of spring B is (5//6) of its total length. Both springs are of equal lengh initially :
