Problem and Solution Mechanics of Materials (Find smallest diameter)

2.12 Rod BD is made of steel E = 29 x 10⁶ psi and is used to brace the axially compressed member ABC. The maximum force that can be development in member BD is 0,02 P. If stress must not exceed 18 ksi and the maximum change in length of BD must not exceed 0,001 times the length of ABC, determine the smallest diameter rod that can be used for member BD

Guru Solution

Considering stress

Considering deformation

Larger area governs
