Product Code : SCL-PLE-11597
Quick Answer: The Coupled Pendulum Model hangs two identical pendulums from a horizontal wooden rod on a mild steel frame, so that the swing of one passes gradually to the other and back, showing energy exchange between coupled oscillators.

Key Features
- Heavy-duty mild steel frame.
- Horizontal wooden coupling rod held on high-tensile thread.
- Two identical pendulums hung at equal distances.
- Shows the alternating rise and fall of amplitude (beats).
- Supplied ready to use.
Technical Specifications
| Specification | Value |
|---|---|
| Frame | Heavy-duty mild steel |
| Coupling | Horizontal wooden rod on high-tensile thread |
| Pendulums | 2, identical, at equal distances |
| Suspension | Thread mounting |
| Supplied | Pre-configured, ready to use |
How It Is Used
One pendulum is set swinging while the other starts at rest. Through the shared rod, energy passes to the second pendulum, whose amplitude grows as the first dies away, and the exchange then reverses. The repeated rise and fall of amplitude is used to discuss resonance, coupled oscillation and beats.
Frequently Asked Questions
What does the Coupled Pendulum Model demonstrate?
The transfer of mechanical energy between two identical pendulums linked by a horizontal wooden rod. The amplitude of one grows as the other's falls, then the exchange reverses, which is used to study resonance and beats.
