QUESTION:

Link BD is made of brass (E = 105 GPa) and has a cross-sectional area of \(240 \mathrm{~mm}^{2}\). Link CE is made of aluminum (E = 72 GPa) and has a cross-sectional area of \(300 \mathrm{~mm}^{2}\). Knowing that they support rigid member ABC, determine the maximum force P that can be applied vertically at point A if the deflection of A is not to exceed 0.35 mm.
