The phrase "allows them to rotate" is correct and usable in written English.
It can be used in contexts where you are describing a mechanism or system that enables objects or elements to turn or spin.
Example: "The new design of the fan allows them to rotate at different speeds for optimal airflow."
Alternatives: "enables them to spin" or "permits them to turn."
Instead of being locked solidly together, the flywheel and transmission shafts are coupled using a viscous fluid which allows them to rotate at different rates but gently brings them into sync.
The new technique enables scientists to move the floating object vertically and laterally, but it also allows them to rotate the object, something that previous techniques couldn't do.
A segment known as the "hinge region" joins the two lobes and allows them to rotate.
Sitting frees infants' hands, allowing them to rotate objects, transfer objects from hand to hand, and finger the edges of objects.
Our results show that, following tetrad formation, a delay in the dissolution of the pollen mother cell wall and tapetal chamber is a key event that holds the four microspores together in a confined tapetal chamber, allowing them to rotate and then bind through the aperture sites through small pectin bridges, followed by joint sporopollenin deposition.
3.0: This profile describes players whose trunk control allows them to fully rotate and lean forward, but does not allow them to lean to the sides.
Seven boom models with different geometries and buoyancy weight ratios are tested with an experimental setup that allows them to heave and rotate freely.
While femoral shaft rotational osteotomy does not address the proximal femoral deformity directly, this technique recovers a functional range of hip motion and allows them to walk with their "hip" externally rotated (but foot neutral), thereby mitigating the effects of FAI.
The company's vision represents a striking departure from that of Sir Peter Hall, who founded the Royal Shakespeare in 1961 with the idea of nurturing actors in a repertory ensemble, allowing them to perform in a rotating group of plays for a year or more at a time.
The fan structure at the rear would keep the panels out of view of passengers and pilots, and the single-stem design would allow them to be tilted and rotated to capture the maximum amount of sunlight.
