3. A V-belt drives a pulley at a speed of 1440 m/min. The coefficient of friction between belt and pulley is 0.3, semi V-groove angle is 22.5° and angle of contact of belt with the pulley is 160°. If the mass of the belt is 0.45 kg/m and if permissible pull in the belt is 800 N. Calculate the power. Consider the centrifugal tension in the belt.
