Vibration of Spiral Spring Apparatus- Engineering Lab Training Systems.
Technical Description
A spiral spring made of cold rolled
steel is clamped between a ball bearing mounted shaft and a fixed
bracket. Two levers are fitted to the shaft diametrically opposite each
other. Two sliding weights of metal on the levers can be securely fixed
in position using clamping screws. These form the rotating mass with an
adjustable moment of inertia. The system is displaced by hand. The angle
of rotation is read off on a 1° scale disc that is also attached to the
shaft. The unit is intended for wall mounting.
