18.2 Consider an elliptic-planform wing with an aspect ratio of 8. (Root chord=c, span=2b) The airfoil section is thin and symmetric, but the planform has geometrical twist, a(y)=-4(y/b) degrees, along the Span direction. The geometric angle of attack is geometrical = a +atw• Assume the downwash is the same as the no-twist distribution over the span. [³ 48 20 a) Obtain the lift force versus angle of attack. b) Obtain the induced drag coefficient.

Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.
