The radius bone in the forearm rotates around the ulna bone, which serves as a stable anchor for the radius to pivot on during movements like supination and pronation. The annular ligament helps secure the radius to the ulna, providing stability and allowing for smooth rotation.
The radius bone is so named because of its ability to rotate around the ulna bone, which allows the forearm to rotate. This rotation motion gives the appearance that the radius is "radiating" around the ulna, hence the name "radius."
because they both have different radius ratio so they have different structure. radius ratio=radius of cations/ radius of anions
The radius and the ulna are the two bones that rotate over the wrist. The radius is the bone on the thumb side of the forearm, while the ulna is on the pinky side. They work together to allow the wrist to flex, extend, and rotate.
To rotate the forearm, this is called supination and pronation. The radius has a pivot joint at both ends and rotates over the ulna.
They rotate their wrists.
they are the bones that make up your lower arm. The radius helps the arm to rotate while the ulna supports the arm.

You cannot. If you rotate the circle around its centre, the lengths of the radius and chord will remain the same but the coordinates of the chord will change.
No. If a galaxy were not to rotate, it would soon collapse upon itself, due to its own gravitation.
The rotary effect of a force causing a structure to rotate is called torque. Torque is the measure of the force causing the object to rotate around an axis. It is influenced by both the magnitude of the force and the distance from the axis of rotation.
It obviously depends upon which side you view it from!
