Required information The 4-mm-diameter cable \( B C \) is made of a steel with \( E=200 \) GPa. Knowing that the maximum stress in the cable must not exceed 180 MPa and that the elongation of the cable must not exceed \( 6 \mathrm{~mm} \). If \( a=4 \) \( \mathrm{m} \) and \( \mathrm{b}=4 \mathrm{~m} \), find the allowable load \( \mathbf{P} \) that can be applied as shown. We Ising the FBD/equilibrium equations for member \( A B C \), the tension in the cable \( B C \) can e written as \( \mathrm{P}_{\mathrm{BC}}= \)
