3.  SPRING CONSTANT OF A SPRING

. SPRING CONSTANT OF A SPRING AIM  To determine the spring constant of a spring by using the method of vertical oscillations APPARATUS REQUIRED Spring, rigid support, hook, g mass hanger, g slotted masses, stop clock, metre scale, pointer FORMULA Spring constant of the spring k = 4π M M   where M , M → selected loads in kg  T , T → time period corresponding to masses M and M respectively in second DIAGRAM mass k
