The equilibriation configuration of 3 point masses are connected by springs of equal force onstant is a 45 degree right triangle.
a) Obtain the secular determinant for the mdoes of vibration in the plane and show by rearrangement of the columns that there is a triple root w=0
b) Reduce the determinant to one of third rank and obtain the nonvanishing frequency of free vibration
I did another similar problem but it was 2 masses connected in 1 dimension. I can't wrap my mind around a 2 dimensional problem like this for some reason. Anyone got any tips?
