Answer :
Final answer:
The top and swivel are parts of a lathe's compound rest, and the angular velocity of a lathe can be adjusted to shape materials with precision.
Explanation:
On a Lathe, the top and the swivel are the two main parts of a compound rest. This device is crucial for shaping materials on a lathe. When a piece of wood or metal is placed on a lathe, the angular velocity is determined by the number of rotations per minute (RPM) set by the machine. The radius of the piece affects how the material is cut, as tools are applied to the spinning workpiece to carve and shape it. Moreover, machines like a lathe often incorporate simple machines, such as the wheel and axle, which consists of a rod fixed to the center of a wheel to aid in its function. Angular velocity can be controlled via the lathe's settings, allowing materials to be worked with precision.
