Particle constrained by 4 springs SHM

Click For Summary
SUMMARY

The discussion centers on a point mass constrained to move in the horizontal plane, attached to four fixed pegs by light springs. The springs are arranged at the corners of a square with side length a√2, each having a natural length of a/2 and a spring constant k. The correct angular frequency of the mass executing simple harmonic motion (SHM) is established as ω=√(3k/m), clarifying the misunderstanding regarding the incorrect frequency of ω=√(2k/m). The derivation involves analyzing the forces acting on the mass due to the springs.

PREREQUISITES
  • Understanding of simple harmonic motion (SHM)
  • Knowledge of Hooke's Law and spring constants
  • Familiarity with basic physics concepts of forces and motion

A point mass is constrained to move in the horizontal plane. It is attached to four fixed pegs by four light springs. The four pegs are arranged at the corners of a square of side a√2. Each spring has natural length a/2 and spring constant k.

Show that the mass executes SHM with angular frequency ω=√(3k/m)


Now I keep getting that ω=√(2k/m). I don't understand where the 3k comes from.
