Metacentric Height Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-FML-10026
Jlab Export is a leading Metacentric Height Apparatus Manufacturer,and suppliers in India
Metacentric Height Apparatus (code EL-FML-10026) finds the metacentric height of a stainless steel pontoon, about 300 x 150 mm, floating in a tank of about 600 x 400 x 400 mm with a glass or acrylic front window. A weight slid across the pontoon tilts it, a pendulum pointer on a graduated arc reads the angle of heel, and removable steel strips change the pontoon’s weight. JLab makes this pontoon stability apparatus in Ambala, India.

Calculating GM from the Tilt
With the pontoon floating upright, the sliding weight w is moved a distance x across it, measured on the scale, and the pendulum settles at the angle of heel θ. The heeling moment w x is balanced by the righting moment, giving the metacentric height GM = w x / (W tan θ), where W is the total weight of the floating pontoon including w. Repeating with several values of x, on both sides of the centre line, gives a series of GM values to average.
Stability and Angle of Heel
A positive GM means the metacentre M lies above the centre of gravity G, so the pontoon rights itself after a small tilt; the larger the GM, the stiffer it is in roll. Adding or removing the steel strips changes W and the height of G, which shifts GM. The experiment also follows how the position of M changes with the angle of heel, since the simple formula is valid only for small angles.
Hydrostatics and Floating-Body Apparatus
- Hydrostatic Pressure — forces on surfaces under hydrostatic pressure in water at rest.
- Set for Archimedes Principle Experiment — cylinders and blocks for testing the Archimedes principle of buoyancy.
- Metacentric Height Apparatus — an alternative with a flat-bottomed ship model loaded on deck or base.
The apparatus sits with other hydraulics benches in Fluid Mechanics Lab, a part of Fluid Mechanics and Hydraulics Lab Equipment.
