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 shaft in a circular hole has 2 degrees of freedom: rotation around its own axis and translation along the axis of the hole.
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.
In a torsion pendulum, torsional oscillations are observed. These oscillations involve the twisting of a wire or shaft that suspends the pendulum mass, resulting in a rotational motion back and forth. The restoring force for these oscillations comes from the torsional stiffness of the wire or shaft.
Most hand-held circular saws have no gears--the blade is mounted directly on the motor shaft. The exception is the original-design Skilsaw, which uses a worm gear to drive the blade. (The company makes both styles, today).
Make sure the key is the correct size for the keyway on both the shaft and pulley. Insert the key into the keyway on the shaft. Slide the pulley onto the shaft, ensuring that the key fits snugly into both the keyway on the shaft and the pulley.

(Pi x R x R) x H... Where R is the radius of the shaft and H is the height.
inversly proportioal to cube of diameter
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.
It is the direction in line with (parallel to) the axis of the part. If you have a cylindrical shaft, for example, the axial direction runs along the length thru the center of the circular ends.

There's a secret elevator shaft in China where millions of workers descend and take mine carts until they are under the ocean floor. From there they spin giant turbines that cause the ocean currents to move in a circular flow.
In a torsion pendulum, torsional oscillations are observed. These oscillations involve the twisting of a wire or shaft that suspends the pendulum mass, resulting in a rotational motion back and forth. The restoring force for these oscillations comes from the torsional stiffness of the wire or shaft.
Under torsion only, the shear stress is minimum, in fact zero, at the center point ( where radius is zero)
