Product Code : ILS-AM-10905
Indian Lab Suppliers supplies the Torsion Pendulum (Bridge Type) (Product ID: 10905) as part of its applied mechanics range. A torsion pendulum hung from a tall U-shaped bridge, with an aluminium disc and a fitted iron disc for changing the moment of inertia.
Quick Answer
The main aluminium disc is 15 cm in diameter and hangs on the test wire through a split chuck fitted into the disc, from a tall U-shaped metal bridge that gives a steady suspension. A chrome-plated iron disc about 8 cm in diameter and 1.25 cm thick fits the grooved recess of the larger disc; adding it changes the moment of inertia by a known amount, so periods timed with and without it give the modulus of rigidity of the wire. A larger version has a 25 cm aluminium disc with a 10.5 cm iron disc, 1.25 cm thick.
