Adam Bickerstaff 2/18/09 2. The meaning of a large Q value means that the system is underdamped meaning that the system does not get affected by friction as much which means the amplitude of the oscillations does not change much. A low Q value means that the system is very affected by damping and friction and means that the amplitude of the systems oscillations are greatly affected by friction and amplitude will decrease quicker than a larger Q value. 3. Spring constant K= mass of object*gravity/displacement, so K= (.1kg*9.8m/s²)/(.03m). K thus equals 32.67N/m. resonance frequency of the system is equal to ω (resonance frequency)= (K/mass)^(1/2) so resonance frequency is equal to (32.67N/m)/(.1kg)= 18.07 hz

Unformatted text preview: 4. The phase shift should be small if the ω is small because ω is the angular velocity in radians and phase shift is the displacement of the system in radians. If omega is very small then of course the angular displacement i.e. the phase shift would be small and vice versa if the angular velocity was increased then the phase shift would increase because it would be displaced more. 5. a) find X when ₀ = ω0 ω X =A *Q when ₀ ₀ = ω0 ω b) find θ when = ω0 ω θ = infinity because we take a tan inverse of a function that has 0 in its denominator...
