Spring Constant in Hooke's Law

Click For Summary
SUMMARY

The discussion centers on deriving the equation for the spring constant (k) in Hooke's Law, expressed as k = (m/a²) × (K/ρ)½, where m is the mass of a single atom, a is atomic spacing, K is the bulk modulus, and ρ is the density. Participants seek clarification on the units of the equation and its derivation. A reference link to a related discussion on Physics Forums is provided for further exploration of factors affecting the spring constant.

How does one arrive at the following equation to approximate spring constant for solids... using Hooke's Law
F ∝-x ⇒ F = -kx
and strain∝stress
?

k = (m/a2) × (K/ρ)½

where

k≡spring constant
m ≡ mass of a single atom
a ≡ atomic spacing
K ≡ bulk modulus
ρ ≡ density

Do you have a reference for that equation? The units don't seem to match.

Thread 'A high school physics problem demonstrating relative motion'
I remembered a pretty high school problem from kinematics. But it seems it can help even undergraduates to develop their understanding of what a relative motion is. Consider a railway circle of radius ##r##. Assume that a carriage running along this circle has a speed ##v##. See the picture. A fly ##M## flies in the opposite direction and has a speed ##u,\quad |OM|=b##. Find a speed of the fly relative to the carriage. The obvious incorrect answer is ##u+v## while the correct answer is...
