Product Code : SCL-PL-12128
Resonance Strips Model 7 Metal strips (SKU SCL-PL-12128) is a forced-vibration demonstrator for Class 11 and college physics, with seven spring steel strips of different lengths on one driven base. As the driving frequency rises, each strip in turn swings strongly when the drive matches its own natural frequency. Science Lab Supplies manufactures the frame and strips at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and its quotations go straight to schools, colleges, tender contractors and distributors.
Specifications
Each part of the seven-strip resonance model is set out in the table that follows. In short, tempered spring steel cantilever strips, each cut to its own length, stand on a weighted steel base frame and share one driving axis, with colour-coded tips and a choice of manual crank or external vibrator drive.

Applications and Experiments for the Resonance Strips
The strips make resonance visible: under a slowly rising driving frequency, only the strip whose natural frequency matches the drive shows a large amplitude. That supports Class 11 lessons on oscillations, B.Sc. and engineering mechanics practicals, and talks on structural resonance.
- Class 11 physics: free, forced and resonant oscillations, compared with sympathetic resonance between forks of the Eight-Piece Welch Pattern Tuning Fork Set.
- The relationship between cantilever length and natural frequency, set beside the static bending of the 100 cm bar of the Cantilever Apparatus.
- B.Sc. and engineering labs: sweeping the drive frequency and recording each strip’s resonance point.
Standard Scope of Supply
The apparatus is supplied as a base frame with seven integrated spring steel strips, seven pre-fitted high-visibility tip markers, and an experiment guide with natural-frequency formula tables. An external electric vibrator and its signal source, for powered driving, are separate items for the quotation.
Packing, MOQ and Lead Time
Quotations can be issued for one set for teacher demonstration or several for a practical lab, each stating packing, delivery time and price for that number. As mechanics lab equipment in India, the strips can be quoted with a vibration generator and signal generator for electric driving.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code and is able to ship to buyers in the UAE, Saudi Arabia, Oman, the Philippines, Nepal and Bangladesh. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU).

Frequently Asked Questions
How do the strips show resonance?
All seven strips feel the same drive, but each has its own natural frequency set by its length. When the drive matches one strip, that strip swings with a large amplitude while the others stay nearly still.
Can the strips be driven electrically?
Yes. The driving axis works with a manual crank or an external electric vibrator; with a vibrator and a function generator the frequency can be swept smoothly.
What if a strip gets bent?
A slightly bent strip can be gently flexed back by hand. Avoid pressing down on the strips or over-driving the system, since spring steel can take a permanent set.
Is Science Lab Supplies the manufacturer or a trader?
Strips, frame and drive axis are all produced at the company’s own facility in Saha, Ambala, so this science apparatus manufacturer in India issues every quotation for the model itself rather than through a trader.
Related Oscillation and Resonance Apparatus
Driving the strips electrically needs a vibration generator and a signal source, and resonance and natural frequency also show up well in strings, tuning forks and pendulums. These items from the Physics Lab and Applied Mechanics ranges complete an oscillation bench, and any of them can be quoted together with the strips.
