Answer

$$\tau_{FAIL} = 888.9 \space psi $$

Work Step by Step

Solution: 1) Area of Shear force Distribution: From Diagram in textbook, area of shear force distribution is: $A = 3\space in * 0.6\space in = 1.8 \space in^2$ 2)Failure Stress: $\tau_{FAIL} = \frac{F_{FAIL}}{A} = \frac{1600 \space lb}{1.8 \space in^2} = 888.9 \space psi$ $\boxed{\tau_{FAIL} = 888.9 \space psi} \leftarrow \space\space ANS$
