Abstract

Sound and vibration are mostly invisible, so no wonder solving noise problems is tricky. Mechanical vibration is taught to undergraduates as if it is a simple science. The mass-on-a-spring, uniaxial vibration of a rod, viscous damping, modal analysis - all these are the bread and butter of vibration science. As for rigid-body dynamics (which this talk will dip into) undergraduate courses remain fixed in 2-D planar motion. But real dynamic and vibrating systems just don't behave simply. There are pitfalls in even the most ordinary cases and some of these will be demonstrated: a tuning fork; a bottle of coke; a bending beam; a turbocharger wheel, a bouncing ball ⋯ and boomerangs. All of these things behave counter-intuitively. The paper describes many practical demonstrations - seeing is believing. All are demonstrations that can be repeated at home and they will be shown live at the conference!
