beam goes from 5 V to 3 V after 6 cycles of oscillation. 9. Determine the damping ratio if the peak to peak amplitude of an accelerometer attached to a vibratinga 3 lb weight is hung 15 inches from the mount and a strain gauge is placed 2 in. from the mount on the top of the beam what strain is expected to be observed? (Aluminum 6061-T6 E = 10000 ksi ? = 0.33) 15 in. 2 in. 3 lbs 1 in. 1/8 in. Cross-Section 11. A 1/8 in. thick aluminum bar 1 in. wide is mounted in a cantilevered condition as was done in lab. If
