Three springs with the same constant connected in series and parallel, and a 1-kg object attached at one end of a spring, as shown in figure below. Spring constant is k1 = k2 = k3 = 250 N/m. What is the change in length of the three springs? Acceleration due to gravity is g = 9.806 m.s-2
Solution;
Given;
Object mass,
Acccelaration due to gravity,
Hence ;
Object weight,
Find the equivalent constant;
Such that and are in series ,and whose equivalent is ;
N/m
To find change in length in the springs, ;
