Apparatus for the Study of Harmonic Oscillations Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-9178
Jlab Export is a leading Apparatus for the Study of Harmonic Oscillations Manufacturer,and suppliers in India
This set studies harmonic oscillators, starting with a mass hanging from a spring and moving on to simple, physical and torsion pendulums. Students measure how the period depends on mass, spring constant, length and moment of inertia. It covers most of the oscillation practicals in a school or first-year college course.

Oscillation Practicals for Students and Teachers
For the spring, students first load it in steps with Hangers with Slotted Weights and read the stretch on a Meter Rule held upright beside it. The slope of load against extension gives the spring constant k by Hooke’s law. They then time ten oscillations with a Digital Stopwatch for each mass and check T = 2π √(m/k) by plotting T² against m.
With the simple pendulum, T = 2π √(L/g), so a plot of T² against length gives g. Changing the bob shows that the period does not depend on its mass. The torsion pendulum links period to moment of inertia through T = 2π √(I/κ), where κ is the torsion constant of the wire. Comparing springs from a Springs Set shows the period falling as k rises.
Frequently Asked Questions
Which experiments does the set cover?
It covers elastic oscillations and Hooke’s law, and the period of a spring pendulum against mass and spring constant. It also covers the simple pendulum against length, and the physical and torsion pendulums against moment of inertia. Energy in the oscillation is studied too.
Why time many oscillations instead of one?
A hand-timed start and stop carries a reaction error of a fraction of a second. Timing ten or more oscillations and dividing by the count spreads that error over the whole run, so the period comes out much closer.
Does the amplitude change the period?
For a spring oscillator it does not, as long as the spring stays within Hooke’s law. A pendulum keeps a constant period only for small swings. Larger angles give a slightly longer period, so keep pendulum amplitudes small.
What is the difference between a simple and a physical pendulum?
A simple pendulum treats all its mass as a point at the end of a light string, so only the length matters. A physical pendulum is a rigid body swinging about a pivot. Its period depends on its moment of inertia and the distance from pivot to centre of mass.
How does it compare with the forced oscillation apparatus?
This set studies free oscillations and how the period depends on mass, stiffness and length. The Forced Oscillation and Resonance apparatus drives a spring and mass at set frequencies, free or damped in water, to show resonance.
