    A belt drive consists of two V-belts in parallel, on grooved pulleys of the same size. The groove angle is 30°. The cross sectional area of the belt is 750mm2 and the coefficient of friction is 0.12. The density of the belt material is 1200 Kg/M3 and the maximum permissible tension in the belt is 5250N.
    1) Calculate the power that can be transmitted between pulleys 300mm in diameter rotating at 1500rpm.
    2) Find the shaft speed at which the power transmitted will be at maximum.
