Question: a rigid bar is hinged to a vertical wall...

Question details

A rigid bar 𝐴𝐴𝐴𝐴 is hinged to a vertical wall and supported by steel cable 𝐵𝐵𝐵𝐵 as shown in figure below. Determine the maximum allowable value of the applied load 𝑃𝑃 such that the tensile stress in the cable does not exceed 70 𝑀𝑀𝑀𝑀𝑚𝑚2 ⁄ . The cross-section area of the cable is 625 𝑚𝑚𝑚𝑚2. Also, determine the resulting vertical deflection of point 𝐴𝐴 due to 𝑃𝑃. The modulus of elasticity of the cable material is 20x1010 𝑀𝑀𝑚𝑚2

A rigid bar AC is hinged to a vertical wall and supported by steel cable BD as shown in figure below. Determine the maximum allowable value of the applied load P such that the tensile stress in the cable does not exceed 70 MN/m2. The cross-section area of the cable is 625 mm2. Also, determine the resulting vertical deflection of point C due to P. The modulus of elasticity of the cable material is 20x1010 N/m2 1.5 m 2 m
