Which statement best describes the fleet angle range for a smooth drum?

• A. 0.5 to 1.5 degrees
• B. 1.0 to 2.0 degrees
• C. 0 to 0.5 degrees
• D. 2.0 to 3.0 degrees

Answer: (A)

Fleet angle is the slight tilt between the rope’s path on the drum as it winds and the drum’s axis. For a smooth drum, keeping a small, controlled fleet angle helps the rope lay evenly across the drum face and roll off smoothly without riding up on the edge or weaving back and forth. The best range is about 0.5 to 1.5 degrees because it strikes a balance: enough angle so the rope beds properly and winds evenly, but not so much that the rope experiences uneven contact, edge wear, or tangling during operation. If the angle is too small, the rope may not seat correctly and could bind; if it’s too large, winding becomes uneven and wears the drum edge.
