Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_154

3/154 The 600,000-lb jet airliner has a touchdown velocity \(v = 120 \text{ mi/hr}\) directed \(\theta = 0.5^\circ\) below the horizontal. The touchdown process of the eight main wheels takes \(0.6 \text{ sec}\) to complete. Treat the aircraft as a particle and estimate the average normal reaction force at each wheel during this \(0.6\text{-sec}\) process, during which tires deflect, struts compress, etc. Assume that the aircraft lift equals the aircraft weight during the touchdown.
