However, when a solid formed or machined projection is used, a solid phase forge weld is produced without melting. The plastic deformation of the heated parts in contact produces a strong bond across the weld interface. Below are some examples of projection designs before & after welding -. Fig 2.
Definition of Inequality. An inequality is a mathematical sentence that uses symbols such as <, â¤,=>, or â¥ to compare two quantities. 5 < d=>< 7,= x= â¥= -= 1,=>2 â¤ b, - 12 > - 13 are few examples of inequalities.
An inequality is like an equation that uses symbols for less than(<) and greater than(>) where an equation uses a symbol for is equal to (=). So where the equation: X = Y + 5 says that X is equal to Y plus 5, X < Y + 5 says that X is less than Y plus 5, and X > Y + 5 says that X is greater than Y plus 5. Now I have a problem for you: Substitute the ? in the following expression for the correct inequality symbol: 5 ? 4.
