A driver pulley of 30cm diameter rotates at the speed of 300 rotation per minute and drives a pulley of 45cm diameter mounted on a counter shaft. Another pulley of 40cm diameter is mounted on the same counter shaft by which a pulley of 20cm diameter of a machine is being run. Determine the speed of the machine pulley and also draw the diagram. 6 17. A mould board plough of three bottom, each of which is 30cm wide and 20cm deep, plowing with a speed of 5km/hr. The soil resistance of the land is 0.5kg/cm2. Calculate the total pull of the plow and the horse power required to pull the plow. 6 OR A mould board plough of three bottom of 30cm is plowing 15cm deep. If the speed of the tractor is 6km/h then how much area will it be able to plow in two hours? 10% of the time is being wasted in moving around the edges of the field.
