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.

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.
The degree of freedom for a shaft in a circular hole typically refers to the number of independent movements the shaft can make while being constrained by the hole. In this case, the shaft can generally rotate around its axis (1 rotational degree of freedom) and can also move linearly along the axis of the hole (1 translational degree of freedom). Therefore, the total degree of freedom for a shaft in a circular hole is 2.
a axel
(Pi x R x R) x H... Where R is the radius of the shaft and H is the height.
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.

No, a screwdriver is not a wheel and an axle. A screwdriver is a simple hand tool designed for turning screws and consists of a handle and a shaft with a tip that fits into the screw head. In contrast, a wheel and axle is a type of simple machine that consists of a circular wheel attached to a central rod (the axle), allowing for the movement of objects with less friction. These two tools serve different purposes and operate on different mechanical principles.

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.
