Work that cannot readily be mounted between lathe centers is usually held in a _______________.

Aspindle
Blathe dog
Ccrotch center
Dchuck
AI Explanation

The correct answer is D) chuck. Work that cannot readily be mounted between lathe centers is usually held in a chuck. Chucks are specialized devices that securely grip the workpiece and allow it to be rotated by the lathe. This is essential for holding irregular-shaped or non-cylindrical parts that cannot be easily mounted between the headstock and tailstock of the lathe. The other answer choices are incorrect because: A) a spindle is the rotating shaft in the headstock that drives the workpiece, B) a lathe dog is a device used to drive cylindrical workpieces between centers, and C) a crotch center is a type of live center used to support the workpiece at the tailstock end, not to hold the workpiece itself.
