Question

50 mm 33.7 mm Y 15 mm 33.7 mm P X X Centroid Y A length of 120 mm × 120 mm × 10 mm angle of section shown in the Figeure transmits a longitudinal pull which passes through the point P. Determine (a) the position of the line of zero stress. (b) the maximum value of the pull if the stress on the section is not to exceed 100 MPa. Assume all corners are square. $I_{zz} = I_{yy} = 3.184 \times 10^{-6} m^4$.

Step 1

The neutral axis is the line where the stress is zero. In this case, the section is an angle section, which consists of two flanges and a web. The flanges have dimensions of 50mm x 33.7mm and the web has dimensions of 5mm x 33.7mm. Show more…
