Question 8.10: Compute the approximate maximum shearing stress that would o...

Compute the approximate maximum shearing stress that would occur in a DN80 Schedule 40 steel pipe if it is used as a beam and subjected to a shearing force of 28 kN.

The blue check mark means that this solution has been answered and checked by an expert. This guarantees that the final answer is accurate.

Equation (8–16) should be used. From Appendix A–9(b) we find that the cross-sectional area of the DN80 steel pipe is 1438 mm2 Then an estimate of the maximum shearing stress in the pipe, occurring near the horizontal diameter, is

\tau _{max} \approx 2\frac{V}{A} = \frac{2(28  000  N)}{1438   mm^{2}}  = 38.94 N/mm² = 38.94 MPa
