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. The apparatus comes from the Science Lab Supplies manufacturing unit at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and is sold direct to schools, colleges, tender contractors and distributors.
Specifications
Seven tempered spring steel cantilever strips, each cut to a different length, stand on a heavy steel base frame and share one driving axis. Colour-coded tip markers make the resonating strip easy to spot. The axis can be driven by a manual crank or by an external electric vibrator.

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.
- The relationship between cantilever length and natural frequency.
- 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.

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?
Science Lab Supplies is the manufacturer. As a science apparatus manufacturer in India, it produces the strips and frame at its own facility in Saha, Ambala, and issues quotations straight from there.
Related Oscillation and Resonance Apparatus
Driving the strips electrically needs a vibration generator and a signal source, and resonance is also shown well by strings and tuning forks. These four items from the physics range complete a resonance bench and can be quoted together.
- Vibration Generator — coil-and-magnet vibrator used with a function generator, maximum input 6 V/1 A.
- Signal Generator — signal and function generator for physics teaching.
- Melde’s String Vibration Apparatus — standing waves on a stretched string.
- Tuning Fork Resonance Experiment Kit — sympathetic resonance between matched 440 Hz forks.
