As shown, rod AB is subjected to the loading of two blocks, each of weight W (and where we neglect the mass of the pulley). The loading creates a normal strain in the rod given by ?z=0.020z1/2, where z is measured in inches. This strain corresponds to the total deformation in the rod given by ?B=2.20in.Determine the initial length of the rod, L, measured before the loading is applied.Determine the average normal strain in the rod.?By doubling the magnitude of each of the weights of the blocks to 2W, the total deformation of the rod is double its original value. Determine the ratio of the new initial length of the rod to the original initial length of the rod.?
