Correct option is A
The swing of a lathe is the largest diameter of workpiece that can be rotated on the lathe without hitting the bed. It is a key specification in determining the size of a lathe. The swing is typically measured over the bed and is often listed as the maximum diameter of the workpiece that the lathe can handle.
- Saddle: The saddle is the part of the lathe that moves the tool post along the bed.
- Socket: Socket is a part in various machines but is not related to measuring workpiece capacity.
- Spindle: The spindle is the rotating axis on the lathe but does not determine the workpiece size capacity.
Thus, the correct answer is (a) Swing.
