If a bar of two sections of different diameters of same length are in a line and P load is acting axially on them then what will be the change in length of the bar?
If a bar of two sections of different diameters of same length are in a line and P load is acting axially on them then what will be the change in length of the bar? Correct Answer PL/E x (1/A1 + 1/A2)
Change in length of section 1 = PL1/EA1 Change in length of section 2 = PL2/EA2 Since length is same for both the sections, Total change length of bar = PL/E x (1/A1 + 1/A2).
