Metacentric Height and Stability
Product Code : LSK-FM-10456
Metacentric Height and Stability apparatus (SKU LSK-FM-10456) is a rectangular pontoon that floats in water and lets students find the stability of a floating body with its centre of gravity at different heights, then compare the result with theory. It suits civil, mechanical and marine engineering courses. Pontoon, sail and weights are manufactured by Science Lab Supplies in Saha, Ambala, India, at Plot 448 of the HSIIDC Industrial Area, and the company prices them itself for colleges, contractors and dealers.
Specifications
The pontoon's construction is broken down into single-fact rows below. In short, a plastic sail on the pontoon carries five rows of slots at equally spaced heights; an adjustable weight in any slot shifts the centre of gravity and list angle, which a freely rotating clinometer pointer shows on a scale on the sail.

Applications and Experiments for the Metacentric Height Apparatus
With the apparatus, the list angle produced by moving a known weight sideways can be measured, the metacentric height calculated for each height of centre of gravity, and the results checked against theoretical predictions. It suits hydrostatics practicals in fluid mechanics lab experiments for degree and diploma students.
- B.E./B.Tech civil and mechanical: determination of the metacentric height of a floating pontoon.
- Effect of raising the centre of gravity on stability; a ship-model alternative with a heel pointer reading up to ±15° is the Metacentric Height Apparatus.
- Naval architecture and marine engineering: stability of floating bodies such as ships, rafts and pontoons.
- Diploma courses: buoyancy and the metacentre, introduced with cylinders and blocks from the Archimedes' Principal Demonstration Set.
Standard Scope of Supply
The set comprises the rectangular pontoon, the slotted plastic sail, the adjustable weight, the small trimming weight, and the clinometer pointer with its scale. A water tank to float the pontoon in can be added to the same quotation if your laboratory needs one.
Packing, MOQ and Lead Time
One apparatus can be quoted for a demonstration bench, or several for group practicals. Each quotation sets out packing, delivery time and price for that quantity, and further engineering lab equipment in India from our hydrostatics range can be added.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in the UAE, Saudi Arabia, Oman, the Philippines, Nepal and Bangladesh. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). A pontoon set can be requested with a line on the contact page, kept in the enquiry cart while you add other hydrostatics items, or bid for through the lab tender page.
Frequently Asked Questions
How do students change the centre of gravity?
They fit the adjustable weight into one of the slots on the sail. The five rows sit at equally spaced heights, so the centre of gravity can be raised in steps while sideways slots set the list.
How is the angle of list read?
A clinometer pointer hangs freely at the top of the sail and indicates the tilt on a scale on the sail. A small trimming weight attached to the sail lets students level the pontoon first.
Is Science Lab Supplies the manufacturer or a trader?
Pontoon, sail and weights for this apparatus come from Science Lab Supplies' own factory in Saha, Ambala, India; the set is not bought in for resale, and your quotation is prepared where it is made.
Why is this experiment important?
Stability of floating bodies such as ships, rafts and pontoons matters in many branches of engineering, and the pontoon turns metacentric-height theory into measurements that can be compared with predictions.
