Which of the following is correct?(a) Solid spring shock absorber is heavier than the other types(b) Lift to drag ratio is always unity(c) Weight at takeoff is same as weight at landing(d) Thrust is same as drag alwaysThis question was addressed to me during an interview.Origin of the question is Landing Gear in chapter Landing Gear and Subsystems of Aircraft Design

Answer»

The correct answer is (a) SOLID spring shock ABSORBER is heavier than the other types

Explanation: Solid spring shock absorber is heavier than the other types Lift to DRAG is not necessarily be unit ALWAYS. TYPICALLY, a good design will have lift to drag ratio more than 1. During flight weight decreases and as a result takeoff weight and weight during landing will not be same.
