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 σy = 449 MPa, whereas that used for the rectangular cross- section is 0.7%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= 96 mm, b=43 mm, a=12 mm, H=96 mm, d= 43 mm N b h a Z a | d H

03. Circle the letter corresponding to the view on the right that shows the result of rotating the object on the left by the indicated amount.

The beam in the figure below is subjected to a load P= 3.9 kN at its end. Young's modulus is 210 GPa and the moment of inertia for the beam's cross-section is 5×106 mm4. P If a = 1.5 m and b= 1.3 m, determine: A F a B |-x₂ b Tuc
