First-order lever in which the beam is not straight but bent to form an obtuse angle. Resting on a double base, it is of similar construction to levers inv. 1007 and inv. 1002. Each end carries a lead pan suspended by a cord. The apparatus served to demonstrate that a bent-beam lever functions exactly like a straight-beam lever.

The instrument is inspired by a model proposed by Willem Jacob 's Gravesande in Physices elementa mathematica, experimentis confirmata (3rd ed., Leiden, 1742). Provenance: Lorraine collections.
