Hooke's law establishes that the elongation of a spring is directly proportional to the modulus of the force
applied to it, <u>as long as the spring is not permanently deformed</u>:
(1)
Where:
is the elastic constant of the spring. The higher its value, the more work it will cost to stretch the spring.
is the length of the spring without applying force.
is the length of the spring with the force applied.
According to this, we have a spring where only the force due gravity is applied.
In other words, the force applied is the weigth
of the block:
(2)
Where
is the mass of the block and
is the gravity acceleration.
(3)
(4)
Knowing the force applied
and
and
, we can substitute the values in equation (1) and find
:
(5)
(6)
