Torsion Axle

Axle for investigating rotational oscillation of various test bodies and for determining their moments of inertia from the period of oscillation. With ball-bearing mounted shaft, coil spring and holding lug. The test body is a bar with weights that can be moved along its length and a circular disc with one hole in the centre and eight away from the centre for determining moments of inertia for eccentric axes of rotation and confirming Steiner’s theorem. 

• Deflecting torque of the spring: 0,028 Nm / rad.
