A flat steel bar 6 in wide by 1.5 in thick has axial loads applied with 1.250-in diameter pins in double shear at points A, B, C and D as shown in Figure 1. Determine (a) the axial stress in the bar on a cross section 20” to the left of C (b) the average bearing stress on the bar at pin B (c) the cross shearing on the pin at A. SHOW FBD.
