Calculating the shear flow, q = VQ I q = 480000(57750) 108 × 106 q = 256. 667 N mm SITUATION 2. For the I-section shown: Properties: A = 10800 mm2 Ix = 383.15 × 106 mm4 L = 8 m w = 10 kN/m 1. Calculate the maximum shear in the beam in kN. 2. Calculate the average shear stress in the beam in MPa. 3. Calculate the maximum shear stress in the beam in MPa. Solution: Calculating the maximum shear of the beam, V = wL 2 V = 10(8) 2 V = 40 kN (or 40000 N) The average shear stress in a beam is the vertical shear stress. τ = V dtw τ = 40000 [576 + 2(12)](9) τ = 7. 407 MPa
