A4-m-long rigid beam carrying a 10-kN/m uniformly distributed load is supported by a pinned connection and cable as shown. The beam weighs 2.0 kN. Tensile stress in the steel cable must not exceed 150 MPa. Neglecting the weight of the cable, determine the minimum diameter of the steel cable to the closest 1.0-mm increment (i.e., 10 mm, 11 mm, 12 mm, etc.) without exceeding the maximum specified tensile stress.
