Problem #1: Re-evaluate the beam from the Module 3 homework. Recall that you determine the principal stresses at point A and B on the beam. Note: Assume the yield strength is 248 MPa. Part A: Based on that information, determine if any of the failure criteria (Rankine's theory, Tresca criterion, and Von Mises criterion) predict failure by yielding at either A or B. Present the factor of safety for all three criteria. Part B: Based on the results of Part A and what we know about the failure surfaces of these three criteria, do these computed factors of safety make sense? Where does this data point land on the failure surfaces? 20 kN 100 mm 10 kN B 100 mm 100 mm •B |A 50 mm 50 mm 2 m 2 m
A (160+Reg. No.) kN force is applied as shown at the end of a hot-rolled steel beam. Neglecting the effect of fillets and of stress concentrations, perform calculations in MS excel or MATLAB for the principal stresses in the beam to satisfy a design specification that they be equal to or less than 150 MPa. If the principal stresses are more than the given value, what would you change in the beam so that satisfy the required stresses. 210 mm 13 mm a 1035 mm 110 mm 160kN +Reg No. 0.4m (b) (a) Figure: Hot-rolled cantilever steel beam a) 3D view of the beam b) Cross-section of the beam

Learning Goal: To calculate the shear stress at a point in the web of an l- beam section subjected to a shear force. When a beam section is subjected to a shear load, a shear stress distribution is developed on the section. The distribution of the shear stress is not linear. Elasticity theory can be used to calculate the shear stress at any point. However, a simpler method can be used to calculate the average shear stress across the width of the section, a distance y above or below the neutral axis. The average VQ shear stress is given by T = Here V is the shear It force on the section, I is the moment of inertia of the entire section about the neutral axis, and ₺ is the width of the section at the distance y where the shear stress is being calculated. Q is the product of the area of the section above (or below) y and the distance from the neutral axis to the centroid of that area (Figure 1). In short, Qis the moment of the area about the neutral axis. Figure 1 of 1 An I-beam has a…
