Unformatted text preview: below), plot the real and imaginary parts of: a. (5 pts.) the direct FRF X 2 /F 2 b. (5 pts.) the cross FRF X 1 /F 3 c. (5 pts.) the cross FRF X 3 /F 1 d. (5 pts.) verify that reciprocity holds by comparing your solutions from parts b. and c. k 1 = 4 x10 6 N/m k 2 = 6 x10 6 k 3 = 4 x10 6 k 4 = 2 x10 6 k 5 = 1 x10 6 c 1 = 100 Ns/m c 2 = 200 c 3 = 175 m 1 = 0.7 kg m 2 = 0.9 m 3 = 1.1 Please include your computer code. For your plots, use a frequency range of 0 to 1000 Hz and units of m/N for the vertical axes. 4. (20 pts.) Determine the mass, stiffness and damping coefficients for a SDOF system from the following experimental direct FRF. 5. (20 pts.)
