A proposed interstellar space vehicle comprises an accommodation unit of mass 690 Tons at the front, separated by a light tube between the individual centres of mass, which is 43m. The amount of seperation is necessary to reduce levels (from the nuclear engine) at the accommodation unit. Axes xy are centred on the engine unit centre of mass, with x towards the accomodation unit, and y perpendicular to x. All masses may be considered constant.
Q1 Fund the x coordinates of the centre of mass of the space vehicle.
Q2 The engine operates, giving a thrust of 8.2 MN directly along the connecting tube. Calculate the acceleration, and hence choose one of the following options for the compressive force in the connecting tube.
