It is important when designing ships to ensure that gyroscopic effect of the mounted turbine engine and its direction (torque reaction of the gyroscopic effect) are well identified prior to mounting the engine along with body axis. Your role in a team working in ship manufacturing company is to analyse the mounting process and calculate the required information to prevent any expected gyroscopic effect on the ship navigation line (no unwanted steering of the ship due to gyroscopic torque). Your manger asked you to provide detailed report of your calculations and final professional recommendations after giving you the following information: - The mounted engine rotates anticlockwise at 8000 rpm, when viewed from front. - The moment of inertia of all the rotating parts are 230 kg.m². The ship makes a right-hand turn of radius of 400 m at speed of 2.2 m/s.
