A fidget spinner consists of two circular objects (spinner arms) and a central shaft. The spinner arms spin around the central shaft when flicked, providing a satisfying sensory experience for users.
A shaft in a circular hole has 2 degrees of freedom: rotation around its own axis and translation along the axis of the hole.
A screw is a simple machine that is used to fasten objects together or to lift objects by rotating through a threaded shaft. It is classified as an inclined plane wrapped around a central rod.
Shafts are usually made circular because a circular shape provides the most efficient distribution of stress and load, making them better suited to withstand torsional forces. Additionally, circular shafts are easier to manufacture and maintain compared to other shapes.
A screw is a fastener with a ridged shaft (called a thread) that wraps around a central point. When rotated, the screw moves forward or backward depending on the direction of rotation, making it ideal for holding objects together or securing them in place.
A screw has a threaded shaft and a head. The threaded shaft is designed to twist into a surface to securely fasten objects together. Different types of screw heads are used for specific applications, such as Phillips, flathead, or hex.

An anemometer is a device to measure wind speed. It is usually a series of arms extending our form a turnable central shaft. On the end of each arm is a "cup" which catches the wind. As the wind fills the cups, the arms spin, and thus the central shaft does too. The central shaft is connected to a device which converts turns of the shaft into miles (or kilometers) per hour.

A rack and pinion system is a simple mechanism which converts linear to circular motion. More complex systems such as the pistons of a car engine rotating the drive shaft are common.
The main portion or shaft of a long bone is called the diaphysis.
Osteons are cylindrical structures found in the diaphysis (shaft) of long bones. They consist of concentric rings of bone tissue called lamellae, surrounding a central canal that houses blood vessels and nerves. Osteons are responsible for providing strength and support to the bone structure.
