Given that the three bars shown in the accompanying figure are made of the same material, comparing bar (a) to bar (b) which bar will stretch more, when subjected to the same force F? Bar (a) and (b) have the same cross-sectional area but different length. Comparing bar (a) to bar (c) having the same length but different cross-sectional areas, which bar will stretch more? Explain.
Case 1: Bar (b) will stretch more than bar (a). Note from above equation, F, A, and E are the
same.
Case 2: Bar (a) will stretch more than bar (c). Note from above equation, F, L, and E are the
same.
