About This Product
The needle hangs from the wire under test and is set into torsional oscillation. Swapping the solid and hollow cylinders between the inner and outer positions changes the moment of inertia, and the two oscillation periods give the rigidity modulus of the wire without needing the inertia of the tube itself. Schools, colleges and institutes in Oman, Costa Rica, Guinea-Bissau, Syria, Bulgaria and Moldova can order the Maxwell Vibration Needle from Educational Instrument.
Frequently Asked Questions
What is the Maxwell Vibration Needle used for?
It is used to find the modulus of rigidity of a metal wire by timing torsional oscillations with the brass cylinders in two different arrangements.
What cylinders are supplied?
Two solid brass and two hollow brass cylinders, each 100 mm long, which together fill the tube.
