Question
Simply Supported Beam ABCDE below carries multiple loads as shown. A built-up
section made from a T-Section and a Channel (C-Section) fastened together by 16mm∅ bolts,
equally spaced from the center of the section, with shearing capacity τ=100 MPa, for bearing σb
= 220 MPa for rivets in single shear and σb = 280 MPa for rivets in double shear. E=200GPa for
all materials.
a. Determine the location of Neutral Axis, in mm, from the top of the section.
b. Determine the location of the centroid, in mm, from the left of the section.
