In the last article we learnt the basic concepts of SHM. Now we shall try to visualize the spring mass system. Before that we will see what spring constant is. We know force by a spring is given by,
k is known as the spring constant or stiffness constant.
Unit of spring constant is N/m.
There are different types of spring. For example torsion spring which works due to turning of the spring.
We can also visualize this spring-mass motion with the help of uniform circular motion.
Suppose at \( t\)
How to find spring constant when a number of springs are connected together? Suppose we have a situation as shown below:
Suppose the mass is displaced by x towards right, so the force exerted by S2
Force exerted by \(S_1\)
So the total restoring force \((F)\)
Hence equivalent \(k \)
Using similar approach try to find equivalent spring constant for the following?
Also the time period for the spring mass system can be shown to be,
Where, k is the equivalent stiffness constant.
Stay tuned with Byju’s to learn more about spring constant, SHM and much more.
