Hi, I've just started a degree in Mechanical Engineering after a HNC and im having trouble with the Dynamics module!! The lecturer literally just blabbed on about Free Vibration and did a worked example of a free vibration system with 1 degree of freedom. He didn't tell us any of the equations used or what any of the symbol stood for and i learnt nothing. I've read around for a few hours and got most of the x=displacement, m=mass, omega(n)= natural frequency but i need some worked examples that I can work through in order to get used to working out the questions etc. So basically my questions is does anyone know of any online worked examples that I can try and figure this out with? Thanks in advance for any help, im guessing ive not made a lot of sense here so any help is much appreciated!!!
