Answer»

The CORRECT choice is (a) vertical velocity at touchdown

Explanation: Stroke is defined as the amount of deflection required by SHOCK absorbing system. Deflection required by shock absorber depends upon number of parameters. For example, vertical velocity at touchdown is ONE of the IMPORTANT factor affecting the stroke of the shock absorber. Lift at cruise will be same as WEIGHT at cruise.
