BI. A pulley system, which has a groove angle of 40°, uses a V-belt of cross-sectional area 450 mm² and density 1200 kg/m³ as shown in Figure QB1. The rotational speed of the driving pulley is 1000 R.P.M. The coefficient of friction between the belt and pulley is 0.35. If the maximum force allowed in the belt is 700 N, determine: Ø300 mm A Driven Pulley 550 mm Figure QB1 (a) the angle of lap of both driving and driven pulleys; (b) the mass of the belt per unit length; (c) the velocity of the belt; (d) the centrifugal tension due to the mass of belt; (e) the torque on each of the two shafts; and (f) the maximum power transmitted to the driven shaft.
