Question 676Steam Plants - Assistant Engineer70% to pass
The purpose of shroud bands secured to the tips of the turbine blades is to _______________.
AI Explanation
The correct answer is C) stiffen the blades to reduce vibration.
Shroud bands are secured to the tips of turbine blades to increase the stiffness of the blades and reduce vibration. This helps maintain the blade's structural integrity and prevents excessive blade movement, which could lead to fatigue and potential failure. The other answer choices are incorrect because they do not directly address the primary purpose of shroud bands, which is to reduce blade vibration.
