A B W The rigid beam ABC shown above is supported by a pin connection at C and by steel rod BD, which has a diameter of 12.0 mm. If the normal stress in BD must not exceed 230 MPa. (a) What is the allowable force in the cable? and, (b) what is the maximum uniformly distributed load w that may be applied to beam ABC? Use dimensions of a = 345 mm, b = 740 mm, and c = 555 mm.
