Question 4: 3. 4. Calculate the diameter of the rope assuming (a) a round strand, and (b) a flattened strand rope. Calculate the weight of the rope. Discuss the effect of rope weight on the calculation in Question 2. Estimate the error due to neglecting the rope weight. Use the rope strength and weight formulas in Questions 28 and 29. Repeat solution to Question 3, using two ropes. Formulas from Questions 28 and 29: F-52d2 for round ropes F= 37.7d2 m= 0.36d2 (round ropes) 2 W= 0.00078 d
