Question

The first step of conic construction is __________

(a) selecting desired end points at desired tangent angle

(b) selecting a circle to proceed

(c) selecting ellipse always

(d) selecting parabola always

The question was asked by my college director while I was bunking the class.

Asked question is from Configuration Layout topic in portion Configuration Layout and Loft of Aircraft Design

Answer 1

The correct option is (a) selecting desired end points at desired tangent angle

The explanation: Conic lofting method is a step by step method to generate conic of desired cross-section. In general, first step of any conic development is to fixe two end points of the shape. And based on this endpoint we will fix the tangent point as per our requirement.
