Free Vibration of Beam Spring
Product Code : EL-TOMP-11402
Quick Answer: Free Vibration of Beam Spring is a vibration experiment in which a rigid ladder-type beam, pivoted at its left-hand end, is hung from a spring and set oscillating. A non-contacting displacement sensor measures the oscillations at the right-hand end.
Last updated: October 2026
Key Features
- Back panel fixes to the Test Frame and carries the pivot and sensor
- Ladder-type beam with equally spaced rungs keeps the mass evenly distributed and gives mounting points
- Self-aligning bearings in the pivot let the beam rotate through a small angle
- Spring bracket holds a choice of two springs to suspend the beam from any rung
- Printed scales on the back panel and spring bracket for placing masses, spring and the optional damper

About This Product
Students first use the bracket scale to check Hooke’s Law and find the spring constant. They then pull the beam down gently, release it, measure the frequency of oscillation and compare it with the frequency predicted from theory, moving the spring and masses along the beam to see the effect. Laboratories and colleges in Qatar, Uruguay, Burundi, Jordan and Bahrain can buy the Free Vibration of Beam Spring through an export order.
Frequently Asked Questions
What does the Free Vibration of Beam Spring experiment mount on?
A back panel carrying the pivot and the displacement sensor fixes to the Test Frame.
Can the spring position be changed?
Yes. The spring bracket above the beam lets either of the two springs suspend the beam from any rung along its length.
