What Are Brass Pendulum Bobs Used For?
A simple pendulum is a small heavy bob hung on a light thread from a rigid support. For small swings its time period depends on the effective length of the pendulum and on the acceleration due to gravity, not on the mass of the bob, so timing the swings for several lengths gives a value for g. This is a standard practical in class 11 physics and in first-year college mechanics. A dense brass bob is preferred because its weight is large compared with the air resistance on it, which reduces the effect of air drag on the result.
What to Specify When Ordering
- Bob type — these brass bobs, the 18 mm brass or chrome-plated iron bobs, or spheres in other materials.
- Quantity — for example one per student pair.
- Stand and clamp — the Simple Pendulum set and the Pendulum Clamp are separate items that can be quoted on the same enquiry.
Frequently Asked Questions
Does the mass of the bob change the time period?
No. For small swings the period depends on the effective length and on g, not on the mass, which students can check by changing bobs.
What information is needed for an export quotation?
Send the quantity, whether hooks are required, the destination country and port or city, your delivery terms (for example FOB or CIF), any packing or labelling needs and a tender reference if applicable.
Who manufactures the Brass Pendulum Bobs?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes them at its works in Ambala, Haryana, India, and quotes for them directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of mechanics lab equipment and other physics apparatus in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The bobs are produced at JLab’s own works, not bought in from a trader, so schools, colleges, dealers and importers buy them factory-direct and can reorder matching bobs later. JLab exports worldwide and ships to buyers in every region — for example Libya in North Africa, Malta in Southern Europe, Vanuatu in Oceania, Sri Lanka in South Asia and Armenia in Eastern Europe. Tender buyers can see the JLab lab tenders page.
Pendulum Apparatus
- Simple Pendulum — a ready-to-use set with a brass bob, thread, heavy metallic base, rod and clamp.
- Pendulum Clamp — a clamp that suspends three pendulums at once, each with its own thumbscrew.
- Pendulum Bobs (18mm) — spherical bobs with a hook, in brass or chrome-plated iron.
- Pendulum Bobs or Spheres — solid spheres with hooks in metals, wood or plastic.
