Add mass to end of cantilever beam

Please login with a confirmed email address before reporting spam

Hi, I want to get the natural frequency of a cantilever beam with one end fixed and the other end with a mass. I tried both adding a mass at the end of the beam, and applying a point load. Both approaches give me lower eigenfrequencies (1-2 order of magnitude away from the numerical result). I saw on the forum from previous years that adding point load or boundary load does not affect eigen frequencies, any suggestions on how to continue? Thank you!
