Question 1 of 27070

Q

Turbine disks are commonly attached to the shaft by which of the following methods?

🔍 Key Concepts

• How turbine disks must be aligned and centered on the shaft for high‑speed rotation • Which fastening methods allow for very accurate machining and balancing • The difference between permanent fasteners (like rivets) and methods that allow disassembly for maintenance

💭 Think About

• Think about which method gives the best concentric fit between the disk bore and the shaft for high rotational speeds • Consider how turbine disks are assembled and removed during overhauls—what attachment method would a mechanic need to work with? • Ask yourself which methods might introduce imbalance or stress concentrations at the points of attachment

✅ Before You Answer

• Identify which option provides a uniform contact surface between the disk and shaft rather than a few discrete points of attachment • Eliminate options that would make precision balancing and alignment difficult at very high RPMs • Consider which method is commonly used on high‑speed rotating machinery such as turbines, not slow, heavily built equipment
