Abstract: 
 We consider two inverse problems of determining  point sources in
 vibrating beams by boundary measurements. We show that the boundary
 observation  at one extremity of the domain determines uniquely the
 sources for an arbitrarily small time of observation.
 We further establish  conditional stability results and give
 reconstructing schemes.
