A belt drive consists of two V-belts in parallel, on grooved pulleys of the same size. The angle of the groove is 30°. The cross-sectional area of each belt is 780 mm2 and the coefficient of friction between the belts and the pulleys is 0,12. The density of the belt material is 1,4 Mg/m3 and the maximum safe stress in the material is 7,5 MN/m2. Consider centrifugal tension. Calculate: 2.1 The mass of the belt per metre length. 2.2 The centrifugal tension (Tc). 2.3The maximum tension (T1). 2.4 Tension on the slack side (T2).
