Particle constrained by 4 springs SHM

In summary, a particle constrained by 4 springs SHM is a system where a particle is attached to 4 springs and can only move in a straight line, following the principles of simple harmonic motion. The SHM of this particle is affected by factors such as the stiffness of the springs, mass of the particle, and initial displacement and velocity. Its equation of motion is x(t) = A*cos(ωt + φ), with A as the amplitude, ω as the angular frequency, and φ as the phase angle. The period of oscillation can be calculated using T = 2π √(m/k), where T is the period, m is the mass, and k is the effective spring constant. The amplitude and

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.

FAQ: Particle constrained by 4 springs SHM

What is a particle constrained by 4 springs SHM?

A particle constrained by 4 springs SHM refers to a system where a particle is attached to 4 springs and is allowed to move only in a straight line. The movement of the particle is governed by the principles of simple harmonic motion (SHM).

What are the factors that affect the SHM of a particle constrained by 4 springs?

The SHM of a particle constrained by 4 springs is affected by several factors, including the stiffness of the springs, the mass of the particle, and the initial displacement and velocity of the particle.

What is the equation of motion for a particle constrained by 4 springs SHM?

The equation of motion for a particle constrained by 4 springs SHM is given by x(t) = A*cos(ωt + φ), where x(t) is the displacement of the particle at time t, A is the amplitude of the oscillations, ω is the angular frequency, and φ is the phase angle.

How is the period of oscillation calculated for a particle constrained by 4 springs SHM?

The period of oscillation for a particle constrained by 4 springs SHM can be calculated using the formula T = 2π √(m/k), where T is the period, m is the mass of the particle, and k is the effective spring constant of the system.

What is the relationship between the amplitude and the energy of a particle constrained by 4 springs SHM?

The amplitude and energy of a particle constrained by 4 springs SHM are directly proportional. This means that as the amplitude increases, the energy of the system also increases. This relationship is governed by the law of conservation of energy.
