Mathematical Pendulum Demonstration Apparatus
Product Code : SCL-PL-11840
Mathematical Pendulum Demonstration Apparatus (SKU SCL-PL-11840) is a simple-pendulum set on a mild steel stand, with a bob on a thread, a 50 cm ruler and a digital stopwatch for timing oscillations. Students use it to relate period to length and to estimate g in Class 9 and Class 11 physics and first-year college labs. It is manufactured by Science Lab Supplies in Ambala, India — at Plot 448, HSIIDC Industrial Area, Saha — and goes out directly to schools, colleges, tender contractors and distributors.
Specifications
A 200 x 125 mm mild steel base holds a 500 x 10 mm mild steel rod, from which the bob hangs on a long cotton thread. The spherical bob measures 19–25 mm in diameter; a 50 cm ruler sets the length and a digital stopwatch times the swings.

Applications and Experiments for the Mathematical Pendulum
Students time twenty or so small swings at several thread lengths, square the period and plot it against length. The straight-line graph confirms that period depends on length, not on the mass of the bob, and its slope gives the acceleration due to gravity.
- Class 9 science: measuring time period and oscillations.
- Class 11 physics practical: L–T² graph with a simple pendulum and the effective length of a seconds pendulum.
- B.Sc. mechanics: determining g and checking the small-angle approximation.
Standard Scope of Supply
The apparatus consists of the 200 x 125 mm mild steel base, the 500 x 10 mm mild steel rod, a digital stopwatch, a 50 cm ruler, the pendulum bob of 19–25 mm diameter on its thread, a 150 x 0.1 mm steel rod and a roll of cotton thread for re-stringing.
Packing, MOQ and Lead Time
Because pendulum practicals often run in groups, a quotation can cover one apparatus or one per bench. Each quotation sets out packing, delivery time and price for the chosen quantity, and physics lab equipment in India such as stopwatches can be added.
Holding an Importer-Exporter Code, Science Lab Supplies is in a position to ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). You can write to us from the contact page, use the enquiry cart, or open the lab tender page for bids.
Frequently Asked Questions
What is a mathematical pendulum?
It is another name for a simple pendulum: a small bob on a light thread, treated as a point mass. This apparatus uses a 19–25 mm sphere on cotton thread.
Is a stopwatch included?
Yes. A digital stopwatch comes with the set, together with a 50 cm ruler for setting the thread length.
Is Science Lab Supplies the manufacturer or a trader?
Manufacturer. Science Lab Supplies fabricates the stand and assembles the set at its Saha, Ambala plant in India, and it quotes buyers directly as the producer.
Can sets be quoted for a practical batch?
Yes. State how many benches you need to equip and the delivery address to receive a single quotation for the full quantity.
