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, t₁ = 9mm Flange Width, B, =112.5 mm Web Thickness, tw =9 mm The allowable flexural stress on the beam is 180 MPa. Rivets has a capacity of t= 100 MPa on shear, for bearing, ob-200 MPa on single shear, o,-260MPa on double shear. 1. Determine the location of centroid, y, from top of the beam in mm. 2. Determine the moment of inertia, I, of the section in mm". 3. Determine the maximum allowable moment, Mall, in kn-m, base on the beam's cross-section.

Transcribed Image Text: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, t, = 9mm
Flange Width, B; =112.5 mm
Web Thickness, tw=9 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 shear, o,-260MPA on double
shear.
1. Determine the location of centroid, y, from top of the beam in mm.
2. Determine the moment of inertia, I, of the section in mm“.
3. Determine the maximum allowable moment, Mall, in kn-m, base on the
beam's cross-section.
