A contractor wants to know the maximum length of an ASTM A992 W12×16 they can lift without
damaging the member due to its own self weight. The member will be lifted so that it bends about its
strong axis and secured such that the boundary conditions approximate pinned ends. For this problem,
do not use load or resistance factors.

Expert Solution

Step 1

Write the properties of ASTM A992 W12 $\times$ 16.

$\begin{array}{rcl} mass per unit length, m & = & 16 lb / ft \\ sectional modulus, s_{x} & = & 17.1 {in}^{3} \\ Yield stress, σ_{y} & = & 50 ksi \end{array}$
