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.
To graph an inequality, treat the, â¤ , , or â¥ sign as an = sign, and graph the equation. If the inequality is or, graph the equation as a dotted line. If the inequality is â¤ or â¥ , graph the equation as a solid line. This line divides the xy-plane into two regions: a region that satisfies the inequality, and a region that does not. Next, pick a point not on the line. Check to see if this point satisfies the inequality.
