A rope pulley is designed to transmit 30 kW. Diameter of pulley 360 mm. Speed = 120 rpm. Angle of groove = 45° Angle of lap on smaller pulley = 170°. Coefficient of friction = 0.27. Number of ropes = 10. Mass of the rope = 55 C2 kg/m. Length and working tension of rope is limited to 125 C2 kN, where C is the circumference of rope in meter. Find (i) the initial tension and (ii) diameter of each rope.
