# Finding natural frequency of a steel flat

is there a straight formula for finding one of the natural (preferably fundamental) frequency of a steel flat with dimension say, L=1000 mm, B=100 mm and Thickness T=10 mm ? The flat is fixed at both ends by bolts and two weights of equal magnitude are suspended at 1/4 and 3/4 (i.e. 250 mm and 750 mm) of the flat.

I am yet to find understandable solution to the above problem on the net; so I had to post it to this forum. Please help, I am lost.
