What happens if one rope sits deeper in the sheave groove?

When a rope sits deeper in the sheave groove, it tends to experience increased wear due to the higher pressure and friction against the sides of the groove. This deeper seating can lead to a restricted path for the rope which causes it to rub against the groove more than necessary during operation. Over time, this constant abrasion and friction increase the likelihood of fraying and ultimately failure of the rope, resulting in a shortened lifespan and a greater chance of breaking. Hence, the correct answer highlights that the deeper seating leads to faster wear and tear of the rope, making it more susceptible to breakage.
