A cross-section of a beam is shown in Figure Q2. If the shear force in this section is V = 168 KN, determine the value and the location of the maximum shear stress in the section. In Figure Q2, a = 58 mm and the origin of the coordinate system is at centroid of the cross section. Z a 2a A 4a B- Figure Q2 a a Answer The vertical coordinate (y-coordinate; the y-axis serves as the axis of symmetry of the cross- section.) and horizontal coordinate (z-coordinate) of the location where the maximum shear stress occurs in the section are y= mm; Z= mm; The vertical distance from the location where the maximum shear stress occurs in the section to the bottom side (AB) of the cross section can be calculated as Distance = mm
