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

Turbine disks are attached to the shaft using bolted or welded connections to ensure a strong, positive, and non-slipping joint capable of transmitting high torque and withstanding high rotational speeds. Rivets, pins, locking tabs, and retaining rings are unsuitable for this primary structural connection due to limitations in load capacity and potential for fatigue.
