You are required to perform the following tasks: 1. Sketch a 3D view to show, the ship, spin-axis, precession-axis, the gyroscopic-axis. 2. On the diagram you have drawn, show each angular velocity with its correct direction. 3. On the diagram you have drawn, show the correct direction of the gyroscopic couple. 4. Find the angular velocity of the engine in rad/sec, (on spin-axis). 5. Find the angular velocity of the precession in rad/sec. (on precession-axis). 6. Find the gyroscopic couple in N. m. (on gyroscopic axis).

Project 2:
It is important when designing airplanes 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 airplanes manufacturing company is to analyze the mounting
process and calculate the required information to prevent any expected gyroscopic effect on the airplane
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 clockwise at 1200 rpm, when viewed from front.
The moment of inertia of all the rotating part is 300 kg.m².
The airplane makes a right-hand turn of radius of 5000 m at speed of 1500 km/h.
