Pendulum with a natural frequency

Assignment Help Mechanical Engineering
Reference no: EM13887358

Damping  experiments  on  iron  were  made  using  a  torsion  pendulum   with a natural  frequency  of  0.65  cycles/s.  The  experiments  were  run  at  var- ious temperatures  and  the  maximum  log  decrement  was  found  at  35?C. The activation energy for diffusion of carbon in α-iron is 78.5 kJ/mole. At what temperature would you expect the damping peak to occur if the pendulum were redesigned so that it had a natural frequency of 10 H?
