The rigid block has a weight of 80 kips and is to be supported by posts A and B. These are made of A-36 steel, and the post-C. which is made of C 83400 red brass. If all the posts have the same original length before they are loaded, determine the average normal stress developed in each post when post C is heated so that its temperature is increased by 20∘F. Posts A and B has a cross-sectional area of 8in^2 while post C has a cross-sectional area of 7in^2.
