The Bifilar & Trifilar Apparatus ProDynami - 1302 studies pendulum oscillations using bifilar and trifilar suspension methods. This Bifilar And Trifilar Apparatus tests a stainless steel bar, disk cylinder, and hollow disk cylinder, each with quick-action clamped suspension cords up to 2000mm. It demonstrates both translational and rotary pendulum behavior for determining center of inertia. A full accessory set including stopwatch and measuring scale is included.

Construction and Design
The Bifilar & Trifilar Apparatus ProDynami - 1302 hangs a rectangle bar, a disk cylinder, or a hollow disk cylinder, all made of stainless steel, from a wall mounted plate. Each body has strong steel hooks for attachment to the suspension cords. Suspension cord length can be rapidly changed and securely fixed using clamping screws, with a quick-action clamp supporting lengths up to 2000mm. The disk cylinder measures 160 x 19mm (D x h), with an inner diameter of 100mm, a mass of 3kg, and a height of 41mm. The hollow disk cylinder has an outer diameter of 160mm and a mass of 4kg. The beam oscillates by translation in the plane of suspension like an ideal mathematical pendulum, while the cylinder and circular ring work as rotary pendulums.
Scope of Delivery
