Which of the following is correct?(a) The solid spring year deflects with some lateral motion(b) Lift is always same as weight(c) Drag polar shows lift variation with velocity(d) Thrust loading at landing is same as wing lift alwaysI have been asked this question during an interview.Question is taken from Landing Gear topic in portion Landing Gear and Subsystems of Aircraft Design

Answer»

The CORRECT option is (a) The solid spring year deflects with some LATERAL motion

The best I can explain: Some lateral motion can be OBSERVED when we deflect solid spring. Lift is same as weight during cruise. Drag polar does not show lift variation with VELOCITY. Thrust loading is ratio of Thrust and weight which cannot be same as lift.
