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. With it, students can relate period to length and estimate g in Class 9 and Class 11 physics and first-year college labs. Science Lab Supplies manufactures the apparatus at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and prices it for schools, colleges, tender contractors and distributors from that address.
Specifications
Stand sizes, bob diameter and timing parts of the pendulum apparatus are listed separately in the table. In short, a 200 x 125 mm mild steel base holds a 500 x 10 mm mild steel rod, the 19–25 mm spherical bob hangs on cotton thread, and a 50 cm ruler and digital stopwatch measure length and time.

Applications and Experiments for the Mathematical Pendulum
Students can 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, with longer lengths set on a 100 cm stick from the Measuring Rulers Set.
- Class 11 physics practical: L–T² graph with a simple pendulum and the effective length of a seconds pendulum, adding the bob radius measured on a Vernier Caliper.
- 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
A quotation can cover one apparatus for demonstration or one for every bench in a group practical. Each quotation sets out packing, delivery time and price for the chosen quantity, and physics lab equipment in India such as extra 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). Pendulum sets for a whole batch can be priced from a message on the contact page or a submitted enquiry cart; the lab tender page covers bid purchases.
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 and a roll of cotton thread for re-stringing the bob.
Is Science Lab Supplies the manufacturer or a trader?
The steel stand and the complete pendulum set are produced at the Science Lab Supplies plant in Saha, Ambala, India, and buyers are quoted by the company as manufacturer, without a trader in between.
Can sets be quoted for a practical batch?
Yes. State how many benches you need to equip and the delivery address, and you will receive a single quotation covering packing, delivery time and price for the full quantity.
