4. The rigid link is supported by a pin at A, a steel wire BC having an unstretched length of 300 mm and cross-sectional area of 20 mm², and a short aluminum block having a length of 100 mm under no load and cross-sectional area of 40 mm². If the link is subjected to a vertical force of 550 N as shown, determine the force in wire BC and the aluminum block, and the rotation of the link about pin A. Est = 200 GPa, EAI = 70 GPa.
