Athe locating pin
Bwire springs
Cthe drive pin
Dthe use of an acme thread screw
AI Explanation
You are correct, the answer is A) the locating pin. The locating pin is responsible for forcing the disk stack and tubular shaft to rotate at the same speed as the bowl in a lube oil centrifugal purifier. This ensures that the separation process occurs efficiently, as the components need to spin together to effectively remove contaminants from the lubricating oil. The other options are incorrect because wire springs, drive pins, and acme thread screws are not the primary mechanisms used to synchronize the rotation of the disk stack and shaft with the purifier bowl.
