Nonprismatic Cantilever Bar Has an Internal Cylindrical Hole of Diameter $d / 2$

question 13

Multiple Choice

nonprismatic cantilever bar has an internal cylindrical hole of diameter $d / 2$ from 0 to x, so the net area of the cross section for Segment 1 $\text { is } ( 3 / 4 ) A \text {. Load } P \text { is applied at } x \text {. }$ $\text { and load } - P / 2$ is applied at x 5 L. Assume That E is constant. The length of the hollow segment, x, required to obtain axial displacement δ 5 PL/EA at the Free end is:

• A) \(x = L / 5\)
• B) \(x = L / 4\)
• C) \(x = L / 3\)
• D) \(x = 3 L / 5\)
