This document contains a question paper for a mechanical engineering examination with multiple choice and numerical problems related to dynamics of machinery. It includes 15 questions with topics such as: virtual work principle, unbalanced forces and couples, forced damped vibration systems, governors, gyroscopic effects, flywheel moment of inertia, and torsional pendulum vibration. The questions require calculations of net thrust on a piston, flywheel rim design, balancing of rotating masses, primary and secondary forces in a multi-cylinder engine, shaft vibration amplitudes and dynamic forces, moments of inertia, and gyroscopic couples in rotating ship machinery.
