The coefficient of kinetic friction between the rope and the two bars is 0.28. 1. If F = 10 kN, and α = 30⁰, calculate the force T (kN) necessary to pull the rope downward at a constant rate. A. 3.27 C. 8.43 B. 9.42 D. 12.42 2. If F = 10 kN, and α = 20⁰, calculate the force T (kN) necessary to pull the rope downward at a constant rate. A. 4.3 C. 10.2 B. 33.3 D. 14.3 3. If the force necessary to pull the rope downward at a constant rate is T = 25 kN, and α = 25⁰, calculate the required F (kN). A. 24.12 C. 16.63 B. 10.35 D. 20.41 Thanks for watching!
