A 150 lb person sits on a spring-mounted chair whose spring has a stiffness of 200 lb/in. How far does the chair sink when the person sits down? To set up this problem I would use Hooke's Law: $F(x)=kx$. I know I am looking for the distance the spring moves - so I'm looking for $x$. Would ...
Hooke's law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance x scales linearly with respect to that distance. That is:
F
s
=
k
x
{\displaystyle F_{s}=kx}
, where k is a constant factor characteristic of the spring: its stiffness, and x is small compared to the total possible deformation of the spring. The law is named after 17th-century British physicist Robert Hooke. He first stated the law in 1676 as a Latin anagram. He...
