Rotating System on Air Bed Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12613
Jlab Export is a leading Rotating System on Air Bed Manufacturer,and suppliers in India
Rotating System on Air Bed (code EL-PL-12613) is a rotational-dynamics set in which a disc with a cross bar floats on a cushion of air and is turned by a thread wound on a multiple pulley, with driving torques from 0.05 to 0.60 mN m. A 0–360° protractor scale with 1° divisions tracks the angle turned. The complete set is made by JLab in Ambala, India.

How the Air Bed Removes Friction
The compressor pushes air through the silicone tubing into the bed, and the disc rides on the thin layer of air beneath it, so almost no friction acts against the rotation. The by-pass valve on the tubing bleeds off part of the flow, so the cushion can be set just high enough for free running. Level the bed first with the levelling screws and the levelling disc; on a tilted bed the disc drifts towards the low side.
Torque, Angular Acceleration and Moment of Inertia
A thread from the multiple pulley runs over the pulley to an S-shaped hook carrying weights. When the release mechanism lets go, the falling load applies a steady torque, close to τ = mgr when its acceleration is small compared with g, where r is the radius of the pulley step in use, and the disc speeds up uniformly. Timing how long the disc takes to turn through a chosen angle from rest gives the angular acceleration from θ = ½αt², and Newton’s second law for rotation, τ = Iα, then gives the moment of inertia.
Changing the pulley step or the load varies the torque, and the moment of inertia runs from 0.16 g m² for the disc with cross bar to a 7.1 g m² maximum, so each can be changed with the other held fixed.
