Construction and System Design
The FX-506 is built on a rigid metal carrier that forms both the structural base and the inclined track surface. The three-point support system, combined with two integrated spirit levels, allows the track to be levelled precisely on any standard bench surface before the angle of inclination is applied. Inclination is set by turning the dedicated adjustment bolt, with the built-in inclinometer providing a continuous angular readout based on the plumb line principle, eliminating the need for a separate protractor or angle gauge.
The track surface incorporates a 1000 mm ruler printed or engraved directly along its length, giving an immediate distance reference for timing experiments. The two discs, 70 mm diameter at 380 g and 100 mm diameter at 650 g, are manufactured from steel and each fitted with a 10 mm rotary axis carrying self-centering conical pins. These pins engage with the track edges to ensure the disc starts from a consistent, centred position on each trial.
For pendulum-based moment of inertia determination, the pendulum block is attached to the disc assembly and the system is allowed to oscillate freely. The period of oscillation is recorded using the included stopwatch, and the moment of inertia is calculated from the pendulum equation. The lock pin is used to hold the disc in a fixed starting position before each rolling trial, ensuring a clean, consistent release.

Frequently Asked Questions
Q1: What is the rolling disc on inclined plane apparatus used for?
The FX-506 is used to study rotational dynamics and determine the moment of inertia of disc-shaped rotating masses. By rolling discs of known mass and diameter down a precisely inclined track and measuring travel time over a set distance, students calculate angular acceleration and derive the mass moment of inertia experimentally. The unit also supports pendulum-based moment of inertia determination as an independent verification method.
Q2: What is the moment of inertia, and how is it determined using the FX-506?
The moment of inertia is a measure of a body's resistance to angular acceleration about a given axis, the rotational equivalent of mass in linear motion. Using the FX-506, it is determined by two methods: first, by measuring the time for a disc to roll a known distance down the inclined plane and applying the equations of rotational dynamics; and second, by attaching the pendulum block and measuring the period of oscillation of the disc-pendulum system.
Q3: Why does the FX-506 include two discs of different mass and diameter?
The two discs, 380 g at 70 mm diameter and 650 g at 100 mm diameter, allow students to conduct comparative experiments. Since the moment of inertia depends on both the mass and the distribution of that mass relative to the axis of rotation, using discs of different geometry allows students to observe how these parameters independently affect rolling acceleration and angular momentum.
Q4: How is the angle of inclination set and verified on the FX-506?
The angle of inclination is adjusted by turning a dedicated adjustment bolt on the metal carrier frame. The resulting angle is read directly from the built-in inclinometer, which operates on the plumb line principle, a suspended pointer aligns with a graduated scale to indicate the angle without requiring any external measuring instrument. Two integrated spirit levels confirm that the track is laterally level before the inclination is applied.
Q5: What is included in the scope of delivery for the FX-506?
The FX-506 is supplied as a complete experimental kit including: one inclined plane experimental unit with built-in inclinometer, spirit levels, and integrated 1000 mm ruler; two steel discs (70 mm / 380 g and 100 mm / 650 g) with self-centering conical pins; one stopwatch for time measurement; one lock pin for controlled disc release; and one instructional manual covering experimental procedures and data recording guidance.
