Description This subject looks at how non-rigid components deform and oscillate. It looks at undamped and damped systems undergoing free vibration, steady state forced vibration and transient forced vibration. The principles of virtual work are used to investigate the equilibrium and dynamics of mechanisms.

## Learning Outcomes

On successful completion of this subject, students should be able to:

1. Use Virtual work to determine the equilibrium position of a mechanism.
2. Calculate the acceleration of a mechanism subjected to an applied force or torque.
3. Model a real world system as a collection of simple mechanical components.
4. Determine the equation(s) of motion for a system of simple mechanical components.
5. Solve the equation of motion for a free, 1dof system.
6. Calculate the response to a forced vibration.
7. Balance a rotating disk.
8. Use Laplace transforms to determine the response to impulse and step forces.
9. Take measurements in the real world, and use them to verify the theory presented in the lectures.
