Question
Situation 1| An overhang beam is loaded as shown below. The beam cross-section was built by attaching two (2) channels to a 9mm thick plate using 16mm rivets The property of the channel is given below:
Depth, D=225 mm Flange Thickness, tf=9mm
Flange Width, B=112.5 mm Web Thickness, tw9 mm
The allowable flexural stress on the beam is 180 MPa. Rivets has a capacity of t 100 MPa on shear, for bearing, o.-200 MPa on single sheer, a-260MPa on double shear
1. Determine the location of centroid, ȳ, from top of the beam in mm
