Question

calculate this ;

1. The numerical value of plastic section modulus of the solid rectangular section is

??3

 

2. The numerical value of plastic moment of the solid rectangular section is

N.mm

 

 

 

 

 

The channel shape cross-section and the rectangular cross-section shown in the Figure
Q4 are made of materials with elastic-perfectly plastic behaviour. The yield stress of the
material used for the channel shape cross-section is oy= 407 MPa, whereas that used
for the rectangular cross-section is 0.90 y.
Compute the thickness of the web, t, of the channel shape section if the two cross
sections have identical plastic bending moment about the z-axis.
In Figure 4, h= 80 mm, b=42 mm, a=11 mm, H=80 mm, d= 42 mm
