The rigid link is supported by a pin at A, a steel wire BC having an unstretched length of 200 mm and cross- sectional area of 22.5 mm, and a short aluminum block having an unloaded length of 50 mm and cross-sectional area of 40 mm. If the link is subjected to the vertical load shown, determine the average normal stress in the wire and the block.
