Rods \(A B\) and \(A C\) have a diameter of \(20 \mathrm{~mm}\) and are made of 6061-T6 aluminum alloy. They are connected to the rigid collar \(A\) which slides freely along the vertical guide rod. If the \(50-\mathrm{kg}\) block \(D\) is dropped from rest at a height of \(h=200 \mathrm{~mm}\) above the collar, determine the maximum normal stress developed in the rods.
