• Metallic rod with white and yellow demonstration subdivision.
• Length: 585 mm.
• 20 equidistant pins to hang spring balances, balance pans or weight holders with slotted weights and hook weights.
• Hole with cross-groove at the centre of gravity (indifferent balance).
• Either bolt with pin or bolt with knife edge are suitable for suspending the lever.
• In order to demonstrate stable and unstable balance, two supplementary holes are placed above and below the hole at the centre of gravity.
