1 SOLID MECHANICS DYNAMICS TUTORIAL NATURAL VIBRATIONS ONE DEGREE OF FREEDOM This work covers elements of the syllabus for the Engineering Council Exam D225 DYNAMICS of Mechanical Systems, C105 Mechanical and Structural Engineering and the Edexcel HNC/D module Mechanical Science. Oscillations with two degrees of freedom are covered in other tutorials and these are vital for those sitting exam D225. On completion of this TUTORIAL you should be able to do the following. Explain the meaning of degrees of freedom . Define and explain Simple Harmonic Motion. Explain the meaning of free vibrations.

1.4 ANGULAR FREQUENCY, FREQUENCY AND PERIODIC TIME ω is the angular velocity of the wheel but in any vibration such as the mass on the spring, it is called the angular frequency as no physical wheel exists. The frequency of the wheel in revolutions/second is equivalent to the …
