WELDING OF CAST IRON Cast iron is an extremely versatile material‚ used in thousands of industrial products. It is hard‚ wearresistant‚ and relatively inexpensive. Like steel‚ it is available in many different grades and compositions. While we usually think of cast iron as being brittle (having low ductility)‚ this is not true of all cast irons‚ as we shall see shortly. Cast iron‚ like steel‚ is an iron-carbon alloy. In composition and structure‚ and in some of its properties‚ it is quite different

difficult tasks can be easily done. The results of unity are many. By living united‚ people can enjoy a tension free life in the society. It is also said that ‘united we stand‚ divide we fall’. It is true that we can break a single stick easily but not a bundle of sticks. In the time of flood‚ cyclone‚ earthquake etc.‚ people suffer a lot. To help our fellow beings‚ united efforts is must. For the development of a country united efforts is must. Today our world requires a lot of unity among nations

demonstrate the calculations from Trial 1 at 0° and Trial 1 at 45°. In this experiment we did five separate shots from the cannon at 0°‚ and 3 separate shots at 45°. We determined the average distance of the shots from each angle by using a meter stick. We were then able to calculate the velocity of the shots by dividing the time from distance. After getting the results‚ the distance from the shots fired at 45° had a greater distance from the shots fired at 0° horizontally. This is because as the

The articles of confederation weren’t working so the constitutional convention was finally held in order to draft the
