Problem 2 Consider a rigid triangular frame with three point masses, an m located at FA = as? + 204] a2, a 2m located at FB = of: a?) a2 and a 3m at F0 = a,:% + (12, all displacement vectors relative to the center of mass. Express the moment of inertia matrix for each of the three masses, and add them to get the matrix for the whole system. Someone claims that the principal directions will be 3}, :E | 2, and : _ 2. Check if this is true, and if so, give the associated moments of inertia
