Example 7: The rotor of a jet airplane engine which is supported by two bearings is shown in figure 2. The rotor assembly including compressor, turbine, and shaft has a mass of 1000 kg and a radius of gyration of 250 mm. Determine the maximum bearing force as the airplane undergoes Jiay a pull-out on circular curve whose radius is 2,000 m at a constant speed of 1,000 km/ hr and the engine rotor speed is 10,000 rpm CW as seen from bearing 1. Include the gyroscopic, centrifugal as well as the weight effects. Assume the engine have a mass center at the middle of the assembly and it is 0.1 m above the airplane base.
